> 3M does not provide product information on which filters are best for government repression
Just get the one that everyone else does: NIOSH TC-84A-0510 with protection against "Solid Particles, Organic Vapors, Acid Gases, Ammonia, Formaldehyde, Methylamine". Every lab buys this filter, or its manufacturer equivalent, for dealing with god-knows-what, because this one will handle just about anything.

TC-84A-0510 is not a product. It is a certification for half-face masks + filter combos. The relevant certification for fullface masks+filters is TC-84A-070. (TC-84A-0701 or TC-84A-0704 more specifically)

You need to provide a 3M part number. I had to clean up silicone oil and was looking up which solvent works best while being safe as possible and it turns out to be Ethyl Acetate. It works well but is quite potent. A few whiffs had me dizzy to the point where I almost lost balance so I immediately stopped and ordered PPE. I bought a 3M 6900 full face mask and 3M 60928 NIOSH filters for organics and acids. I could not smell anything, breathing was very smooth and natural, and no fogging. When I was finished I walk about 20 feet from the project, took the mask off and immediately was smacked in the face with the solvent fumes.

I would definitely do a full-face mask. You can buy them at Lowes for painting. The half masks do nothing to protect your eyes. Also try to get Pxx filters as they withstand oils. Some chemicals are oil-soluble and normal Nxx cartridges can’t handle more than one exposure.

The one issue is that a single air bottle has a finite and not particularly long use time (if you're in good shape and don't panic, 20-30 minutes tops).

Put aside politics and anti-tear gas use cases: everyone should just have a full face gas mask for all hacker-ish activities, like painting. Skip half-face, go for full face. Half face models don't just leave eyes exposed but hurts the back of the neck. Maybe I'm wearing it wrong, but the headstrap for full face is much more comfortable. They also seal a lot better.
More random tidbits: You'd semi-obviously want a sacrificial wrap over the mask if you're painting, as well as few spare cartridges. There are particulate filters that are just regular paper masks, organic vapor cans for painting, and couple of acid cans for toxic gases. DYOR and use the right one for the task. Particulate filters go on top of gas cans on the iconic 3M 6000 series masks; it's not integrated to the can. The cans also technically only last few hours after opening the package, so technically you should be replacing twice daily. They also can't protect against large amounts of toxic substances like videogame thick green vapors of alien weapons, only what's somewhat casually filtered. In e.g. inside an active volcano, go for full scuba or something that don't rely on filtering. The reason why some masks use pair of cans as opposed to one can, is just for easier breathing. The performance on paper is the same; you can seal off one port with something if you want. The improvement is maybe not negligible, but you get used to breathing through masks quickly anyway. The mini mask that covers mouth and nose inside a full face mask exists to help clear condensation by forcing you to breathe in fresh air around its front surface and force exhalation through the exhaust valve. Removing it will steam up the shield. The air drawn in is filtered, but exhaust is not; if the wearer is infected with something, the mask won't help stop the spread.
TL;DR: gas masks is its own mini rabbit hole.

Not everyone who wears eyeglasses, unless you're prepared to add another several hundred dollars for the lens holder and set of prescription lenses.
I do have the 3M 6800 full face respirator but almost never use it. The silicone 7xxx series is much more comfortable than the rubber 6xxx series, and the 750x silicone half mask is reasonably priced. Augment with comfortable googles as necessary (vented ones work for me since I'm painting, not rioting).

BUT you need to worry about mucus membranes (ie eyeballs can absorb some chemical). The A1 bit means that it'll protect against PPM that are less than 1000, (No I don't know what the PPM of teargas is.)
I guess but cannot assert that decent hardened safety goggles will help against gas in the eyes, but again you'll need to look at the standards for that. the all in one mask/face shields are a better bet.
Your local hardware store should carry this kind of stuff, especially if they do any kind of plastic solvent or fibreglass/epoxy stuff.

If you are the kind of person who has forgone wearing a mask or eye protection while working on a project because you thought you could be done quickly or it was too much of a hassle or too uncomfortable for the "little" amount of benefit it would have: get a full-face mask.
Full-face masks are so much more comfortable, so much clearer to see through than those stupid yellow sunglasses that get scratched up all the time, so much easier to put everything on, so much better in every aspect that you won't think twice about it anymore. You walk into the shop, grab the one thing, put it on, and get to work.

One of the things this article doesn't cover is how resistant to "non-lethal" ammunition these gas masks are. That's something to keep in mind if you want to take this article seriously.

> 3M does not provide product information on which filters are best for government repression
That would be the 3M™ Organic Vapor/Acid Gas Cartridge/Filter 60923 [0]. Replace after each exposure or 30 days after opening the sealed packaging for best results. A clean shave is important for a good air seal.
The absolute best protection would be a PAPR (powered air-purifying respirator) with a TR-6530N filter [1] installed. Something like the 3M Versaflo M-407SG[2] would fit the filter and provide impact resistance. It can be fitted with a Speedglas 9100XXi [3] (or 9100X/V) auto-darkening filter for protection against flashbangs.
This is an equivalent PAPR [3] with a better form factor which also includes ANSI Z87.1 rated impact-protection (helpful against projectiles) and auto-darkening lenses (helpful against flashbangs/pyrotechnics). It also still works fine even if you keep a beard. I believe this is part of the Optrel Helix product line, which advertises 14-hour battery life. However, the listing I linked does not come with organic vapor / acid-gas filtration. That requires a different form factor for the filter, the Optrel ABE1P Combination Filter [4] offers A1B1E1P certification (Protects against organic gases/vapors, inorganic gases, acid gases, and particulates)
As 'closewith added, "CBRN" or "NBC" masks are also a good option - they are rated for chemical/biological/radiation/nuclear contamination and are available as riot gear with good impact-resistance. Look for A2B2E2K2-P3 ratings / certification.
You could also look into something like the Joseph Leslie Dynamiks A3B3E3K3-rated Jumbo canister for 10000 ppm extended exposure. [5]
I've used the same 3M 6011 (organic vapor) filter for years, for tasks like cleaning with ammonia where I'm not really worried about hazardous exposure just nuisance [0]. And it's lasted just fine (extremely off-label use, of course). So with something like tear gas where you're not worried about actual toxicity per se, I'd think that subjective experience would be fine for knowing when it needs to be changed. If you want to be paranoid, it seems like you could also carry a backup fresh set still in the sealed foil.
With the prices for respirators going up (/me gestures at federal "government" attacking our own cities), if I wanted to save money I'd get a knock-off full face respirator from Amazon (or Ali if you're comfortable transiting the import blockade with this specific item), and then genuine cartridges (NOT from Amazon obviously, lol).
[0] for most things I do, I use the 2097 filters which are primarily particulate with just a small amount of activated charcoal for "nuisance vapors". This is all generally with half-face 7500 bodies.

There's a particulate filter and an organic vapor cartridge, and you're primarily worried about the organic vapor cartridge which has a peel-off seal when you assemble it.
40 hours of use or 30 days, whatever comes first, it says.
It's probably not what I would bet my life on, but I've used a bunch of these up doing wood finishing and cleaning. You swap them when you start to smell anything through the cartridges, because it's not actively handling organic vapors anymore. I think 30-40 hours of real exposure use is realistic.
I typically wipe down & pack masks with organic vapor cartridges into a ziplock bag filled with paper towels when I'm done for the day. This ziplock thing is just what I started doing after leaving it out on the counter and found the cartridges weren't effective the next day. This is entirely unscientific, but I think they last longer stored like this.

I'd say basically all of them in this target market - a respirator with check valves is much more comfortable to use.
For the beginning of Covid I modded my 7500 (half face) to remove the check valve flaps and seal up what would normally be the exhaust ports, making both inhale and exhale go through the 2297 filters. It was harder to breathe, more humid, and developed liquid water accumulation over longer periods.
I would think that if you did the same thing with a full face respirator, it would immediately fog up. If you look at the flow path on them, it's something like atmosphere -> filter -> top face portion -> mouth nose portion -> atmosphere, presumably to keep the part you need to see out of full of dry air.

In many cases, especially for the higher end models, you can spend in the neighborhood of $100 to get an Rx face-shield. On the note of matters that didn't seem to come up much in the article, but that I feel like people should know:
The kind of cartridge you need to withstand teargas is not an N95, as the top comment points out it's quite a bit more involved. The downside of that other than cost and duration of the filter is that you'll feel a lot more resistance on inhaling than you're used to. For some people the combination of something on their face and the feeling of restricted breathing is unbearable, and mid-tear gas attack is a terrible time to realize that.
Consider also that this becomes far more important if you're working hard, say running around or fighting. Anyone who has it in their head to give this a try should keep those factors in mind, as well as get a kit to properly fit-test because again... mid-attack is a terrible time to realize that your fit isn't up to snuff. Likewise with training to don and doff.
In a lot of ways the article feels like clickbait that's extremely self-aware, but not really concerned with the practical reality of what they're implying.

Honestly the 3M 60923 cartridges don't restrict breathing at all. They have great airflow. I've used them all day long in chemical plants, no one complains about that.
mindslight 2 days ago [-]
Seconded. I've used those exact cartridges. Not for as long of shifts as you, but I'd say the face mask fit is much more important for that.
My DIY-perspective tip is that when you're getting to know the respirator, you can take the filter cartridges off and put your hands over the input ports to feel what fully restricted breathing feels like, make it a known sensation in case it ends up happening. Likewise you can cover the output port and breathe out to do a kind of rough fit test.

There is a glasses kit available for the listed 3M 6800.
Just how big are your glasses? These aren't goggles that try to seal around your eye sockets, they are shields that seal around your face, sitting in front of your face by an inch or two. If you're worried about the glasses temple breaking the seal, it's still going to provide the vast majority of benefit.

Yes, in addition to inserts which are custom to the mask, there are small frames with a thin rubber band to keep them on you. They were great for roughhousing occasions as well as under mask. The key part is the thinness and impermeability of the band allows for a good seal.
As someone with big bulky eye glass lenses and frames I looked up the solution for the CM-6 derived masks, https://www.rigad.com/avec-spectacle-insert-for-cm-6-masks. Sounds like you'd have to get new lenses just for it and put 'em in, and the field of view is not great, but it is feasible.

For folks who are actually going to go down this rabbit hole, yes the 3M 6800 series and the GVS respirators are great, and work with very similar cartridge-style filters. That said, a mask alone is not sufficient, and I really recommend you get a Tyvek bunny suit also to protect your skin against chemical exposure. Given the current weather, it's relatively easy to cover over the bunny suit with your outerwear like a hoodie so it's not even necessarily visibly super-obvious, and it will do a lot to help protect you. It's not just your eyes, nose, and mouth you want to protect but every area of your skin ideally.
Also tear-gas canisters are very hot when fired, because tear gas is produced and released via a pyrotechnic reaction inside the canister, basically burning a dry chemical to produce the gas. I recommend wearing a heavy (7mil or 9mil) nitrile glove with your bunny suit and over that wearing leather welding gloves or heat-rated mechanics gloves if you expect to encounter tear gas canisters so you can pick them up and throw them back.
Also, be aware that the filter canisters on most masks are only good for about 45 minutes to 2 hours (depending on exposure levels) when used in an environment where you are actively being exposed to the chemicals you want to filter. You need additional replacement filters that are /sealed/ in their packaging to swap out to in the field. Good luck out there.

You're saying the discussion of which chemical respirators to wear to protests has been had numerous times?
I'd say this is a productive topic of conversation for many HN users. There are not "two sides" on this topic, unless we're talking 3M vs MSA. The people flagging or commenting with opposing political views are disrupting conversation, likely because they they disagree with how the topic has been framed.

The reality is that tear gas is not an effective riot control tool. It works fine against spontaneous mobs of sports fans after their team loses, but it's not especially effective against prepared insurrectionists.
The last time the US faced this level of organized political resistance against lawful federal authority, the Army and National Guard routinely used fixed bayonets to control segregationist protesters. The same technique would work today, but with modern rifles being significantly shorter and hence being less effective bayonet platforms, a dedicated spear might be the better option.
Such weapons, employed in a close-order formation, would be much less lethal than they might seem at first blush. Historical data from 18th and 19th century conflicts shows that, even in battles where bayonet charges happened, there was still an extremely low rate of actual bayonet casualties. Even trained and disciplined soldiers will break and rout rather than let themselves be stabbed with bayonets (or, presumably, spears).

Maybe we should talk about the first time the US had this level of political resistance against "lawful authority". That seems like a better analogy for what's going on here.
Also I feel compelled to point out that "lawful authority" does not imply "authority acting lawfully". The difference is painfully demonstrated by the existence of a thread discussing the use of respirators in response to government jackboots suppressing lawful first amendment activity. The obvious alternative is to let the protests happen, per our Constitution.

This is a genius product review right now for all the reasons everyone else thinks it is. I didn't need to read a single one of the authors personal experiences to understand the underlying message, or read ~100 words about their internal struggles to classify Portland as a riot versus a protest. The lack of brevity and conciseness seriously undercuts the absolute geniusness of maliciously compliant product reviews about gas masks in our current political climate.

No, it's actually you who is the one who is misunderstanding.
The product review, while it does stand on its own, is not the main purpose.
The point is to render absurd the incredulous comments from Pam Bondi, "How did these people go out and get gas masks?" Bondi did not ask this question to receive an answer, "oh, they go to Home Depot and get model X-54-Whatever." The point of her question was to cast aspersion on the protestors, to attempt to delegitimize their grievances by painting them as paid, professional agitators. It's the sort of "I'm just sayin'" bullshit rhetoric we've all had to deal with from racist uncles at Thanksgiving for the last 25 years.
Jeong's article works by failing to engage Bondi's comments on Bondi's grounds. Jeong's use of product review as a structure for her article is a conceit that treats Bondi's comments as a legitimate request for product reviews, side-stepping the concept that only paid professionals could ever know anything about gas masks, because information on the Internet is and wants to be free.

The infighting is so tedious. We really need to peacefully explore the "national divorce" idea again. In the 1860s the concept was too intermingled with the evil of slavery to be considered separately.
But realistically, instead of both sides hating each other to the point of perpetual violence, why not just have 2 or 3 countries in which we can all be happy? Trade and travel agreements are easy to establish by treaty. It doesn't have to be this way.

The idea is still just as intermingled with fundamental human rights, plus the sides are more deeply geographically intermingled than in the 1860s, largely because the victors decided not to really root out the evil they had defeated an instead allowed it to metastasize. There may be no peaceful resolution; there is certainly no possibility of a peaceful divorce.

(I've never been near a tear gas kind of event, but I did witness the Met Police deploy "kettling" for the first time in May 2001, close enough that if I'd not paid attention to the police lines forming up I would have been imprisoned uncomfortably for eight hours.)
If they start rolling through random neighborhoods and gassing people in their homes like they did in Minneapolis, I’d like to be prepared.
I have no personal experience with Mira; I’ve been looking for a respirator myself because I live in Portland.
since the feds are using projectiles on random persons, something that is shatter resistant / impact tested for eye protection should be prioritized. pair with some 60926 filters and you should be good to keep resisting.
More random tidbits: You'd semi-obviously want a sacrificial wrap over the mask if you're painting, as well as few spare cartridges. There are particulate filters that are just regular paper masks, organic vapor cans for painting, and couple of acid cans for toxic gases. DYOR and use the right one for the task. Particulate filters go on top of gas cans on the iconic 3M 6000 series masks; it's not integrated to the can. The cans also technically only last few hours after opening the package, so technically you should be replacing twice daily. They also can't protect against large amounts of toxic substances like videogame thick green vapors of alien weapons, only what's somewhat casually filtered. In e.g. inside an active volcano, go for full scuba or something that don't rely on filtering. The reason why some masks use pair of cans as opposed to one can, is just for easier breathing. The performance on paper is the same; you can seal off one port with something if you want. The improvement is maybe not negligible, but you get used to breathing through masks quickly anyway. The mini mask that covers mouth and nose inside a full face mask exists to help clear condensation by forcing you to breathe in fresh air around its front surface and force exhalation through the exhaust valve. Removing it will steam up the shield. The air drawn in is filtered, but exhaust is not; if the wearer is infected with something, the mask won't help stop the spread.
TL;DR: gas masks is its own mini rabbit hole.
Not everyone who wears eyeglasses, unless you're prepared to add another several hundred dollars for the lens holder and set of prescription lenses.
I do have the 3M 6800 full face respirator but almost never use it. The silicone 7xxx series is much more comfortable than the rubber 6xxx series, and the 750x silicone half mask is reasonably priced. Augment with comfortable googles as necessary (vented ones work for me since I'm painting, not rioting).

This one is good for standard DIY duties that do not involve chemicals (ie cutting, grinding, sanding)
there is a quite readable guide you can get here: https://www.hse.gov.uk/pubns/priced/hsg53.pdf
For chemical resistance: https://www.gvs.com/en/catalog/elipse-a1p3-respirator
BUT you need to worry about mucus membranes (ie eyeballs can absorb some chemical). The A1 bit means that it'll protect against PPM that are less than 1000, (No I don't know what the PPM of teargas is.)
I guess but cannot assert that decent hardened safety goggles will help against gas in the eyes, but again you'll need to look at the standards for that. the all in one mask/face shields are a better bet.
Your local hardware store should carry this kind of stuff, especially if they do any kind of plastic solvent or fibreglass/epoxy stuff.
Full-face masks are so much more comfortable, so much clearer to see through than those stupid yellow sunglasses that get scratched up all the time, so much easier to put everything on, so much better in every aspect that you won't think twice about it anymore. You walk into the shop, grab the one thing, put it on, and get to work.
That would be the 3M™ Organic Vapor/Acid Gas Cartridge/Filter 60923 [0]. Replace after each exposure or 30 days after opening the sealed packaging for best results. A clean shave is important for a good air seal.
The absolute best protection would be a PAPR (powered air-purifying respirator) with a TR-6530N filter [1] installed. Something like the 3M Versaflo M-407SG[2] would fit the filter and provide impact resistance. It can be fitted with a Speedglas 9100XXi [3] (or 9100X/V) auto-darkening filter for protection against flashbangs.
This is an equivalent PAPR [3] with a better form factor which also includes ANSI Z87.1 rated impact-protection (helpful against projectiles) and auto-darkening lenses (helpful against flashbangs/pyrotechnics). It also still works fine even if you keep a beard. I believe this is part of the Optrel Helix product line, which advertises 14-hour battery life. However, the listing I linked does not come with organic vapor / acid-gas filtration. That requires a different form factor for the filter, the Optrel ABE1P Combination Filter [4] offers A1B1E1P certification (Protects against organic gases/vapors, inorganic gases, acid gases, and particulates)
As 'closewith added, "CBRN" or "NBC" masks are also a good option - they are rated for chemical/biological/radiation/nuclear contamination and are available as riot gear with good impact-resistance. Look for A2B2E2K2-P3 ratings / certification.
You could also look into something like the Joseph Leslie Dynamiks A3B3E3K3-rated Jumbo canister for 10000 ppm extended exposure. [5]

With the prices for respirators going up (/me gestures at federal "government" attacking our own cities), if I wanted to save money I'd get a knock-off full face respirator from Amazon (or Ali if you're comfortable transiting the import blockade with this specific item), and then genuine cartridges (NOT from Amazon obviously, lol).
[0] for most things I do, I use the 2097 filters which are primarily particulate with just a small amount of activated charcoal for "nuisance vapors". This is all generally with half-face 7500 bodies.
My own experience is that fit is as/more important than filters, and who knows how well civvies will fit their CBRN gear. It's _oppressively_ uncomfortable!

40 hours of use or 30 days, whatever comes first, it says.
It's probably not what I would bet my life on, but I've used a bunch of these up doing wood finishing and cleaning. You swap them when you start to smell anything through the cartridges, because it's not actively handling organic vapors anymore. I think 30-40 hours of real exposure use is realistic.
I typically wipe down & pack masks with organic vapor cartridges into a ziplock bag filled with paper towels when I'm done for the day. This ziplock thing is just what I started doing after leaving it out on the counter and found the cartridges weren't effective the next day. This is entirely unscientific, but I think they last longer stored like this.
For the beginning of Covid I modded my 7500 (half face) to remove the check valve flaps and seal up what would normally be the exhaust ports, making both inhale and exhale go through the 2297 filters. It was harder to breathe, more humid, and developed liquid water accumulation over longer periods.
I would think that if you did the same thing with a full face respirator, it would immediately fog up. If you look at the flow path on them, it's something like atmosphere -> filter -> top face portion -> mouth nose portion -> atmosphere, presumably to keep the part you need to see out of full of dry air.

The kind of cartridge you need to withstand teargas is not an N95, as the top comment points out it's quite a bit more involved. The downside of that other than cost and duration of the filter is that you'll feel a lot more resistance on inhaling than you're used to. For some people the combination of something on their face and the feeling of restricted breathing is unbearable, and mid-tear gas attack is a terrible time to realize that.
Consider also that this becomes far more important if you're working hard, say running around or fighting. Anyone who has it in their head to give this a try should keep those factors in mind, as well as get a kit to properly fit-test because again... mid-attack is a terrible time to realize that your fit isn't up to snuff. Likewise with training to don and doff.
In a lot of ways the article feels like clickbait that's extremely self-aware, but not really concerned with the practical reality of what they're implying.
My DIY-perspective tip is that when you're getting to know the respirator, you can take the filter cartridges off and put your hands over the input ports to feel what fully restricted breathing feels like, make it a known sensation in case it ends up happening. Likewise you can cover the output port and breathe out to do a kind of rough fit test.
You can hold up a key card to cover each bayonet filter and it seals it perfectly for a quick test at any time.
Good tip, though! I'll have to try that next time I'm using the bayonets.

Also tear-gas canisters are very hot when fired, because tear gas is produced and released via a pyrotechnic reaction inside the canister, basically burning a dry chemical to produce the gas. I recommend wearing a heavy (7mil or 9mil) nitrile glove with your bunny suit and over that wearing leather welding gloves or heat-rated mechanics gloves if you expect to encounter tear gas canisters so you can pick them up and throw them back.
Also, be aware that the filter canisters on most masks are only good for about 45 minutes to 2 hours (depending on exposure levels) when used in an environment where you are actively being exposed to the chemicals you want to filter. You need additional replacement filters that are /sealed/ in their packaging to swap out to in the field. Good luck out there.
Safest to flag (or not) as you see fit, because you are a good person rather than an evil one. Then rely on the admins to rescue needlessly ultraflagged articles as appropriate. They are pretty good at doing the right thing.
I'd say this is a productive topic of conversation for many HN users. There are not "two sides" on this topic, unless we're talking 3M vs MSA. The people flagging or commenting with opposing political views are disrupting conversation, likely because they they disagree with how the topic has been framed. This is exactly like PHP fans going into a Python thread and telling everyone Python sucks, disrupting the people who just wanted to discuss getting things done within the framework of Python. They might have some valid points, but they're not germane to civil discussion.
Automotive Painter shops use an actual filtered external fresh-air feed medical-grade pump, as it avoids whatever mystery compounds are in various paints and cleaners.
Don't cheap out on PPE, as 3M does make good quality filters. =3
The last time the US faced this level of organized political resistance against lawful federal authority, the Army and National Guard routinely used fixed bayonets to control segregationist protesters. The same technique would work today, but with modern rifles being significantly shorter and hence being less effective bayonet platforms, a dedicated spear might be the better option.
Such weapons, employed in a close-order formation, would be much less lethal than they might seem at first blush. Historical data from 18th and 19th century conflicts shows that, even in battles where bayonet charges happened, there was still an extremely low rate of actual bayonet casualties. Even trained and disciplined soldiers will break and rout rather than let themselves be stabbed with bayonets (or, presumably, spears).
I intentionally alternated between left wing / right wing events. These things aren't limited to one side, and they're somewhat frequent, if a bit cyclical.
What if the organizers have drilled it into their heads that they won't use real spears? "WHY DID YOU HAVE REAL BULLETS?!?!?"
Also I feel compelled to point out that "lawful authority" does not imply "authority acting lawfully". The difference is painfully demonstrated by the existence of a thread discussing the use of respirators in response to government jackboots suppressing lawful first amendment activity. The obvious alternative is to let the protests happen, per our Constitution.
If that was actually happening, I would be opposed to it. The only people suppressing lawful first amendment activity were Don Lemon and his friends invading a church, interrupting services, and blocking the exits as they screamed abuse at the parishioners.
Still an amazing story, props to the Verge. But could've been an all time great.

Great writing.
>When I eventually sat down to write my article about the Portland protests, I had a strange kind of epiphany, if it can even be called that. Out in the real world, when drowning in tear gas and adrenaline
Bad writing.
This is a genius product review right now for all the reasons everyone else thinks it is. I didn't need to read a single one of the authors personal experiences to understand the underlying message, or read ~100 words about their internal struggles to classify Portland as a riot versus a protest. The lack of brevity and conciseness seriously undercuts the absolute geniusness of maliciously compliant product reviews about gas masks in our current political climate.
My comment is about the art of subtlety. Again, this is an amazing article, but it's literally just been flagged by HN because it waxes poetic about politics instead of allowing all of that to be there without saying it. We can all read between the lines.
The product review, while it does stand on its own, is not the main purpose.
The point is to render absurd the incredulous comments from Pam Bondi, "How did these people go out and get gas masks?" Bondi did not ask this question to receive an answer, "oh, they go to Home Depot and get model X-54-Whatever." The point of her question was to cast aspersion on the protestors, to attempt to delegitimize their grievances by painting them as paid, professional agitators. It's the sort of "I'm just sayin'" bullshit rhetoric we've all had to deal with from racist uncles at Thanksgiving for the last 25 years.
Jeong's article works by failing to engage Bondi's comments on Bondi's grounds. Jeong's use of product review as a structure for her article is a conceit that treats Bondi's comments as a legitimate request for product reviews, side-stepping the concept that only paid professionals could ever know anything about gas masks, because information on the Internet is and wants to be free.
But realistically, instead of both sides hating each other to the point of perpetual violence, why not just have 2 or 3 countries in which we can all be happy? Trade and travel agreements are easy to establish by treaty. It doesn't have to be this way.
The idea is still just as intermingled with fundamental human rights, plus the sides are more deeply geographically intermingled than in the 1860s, largely because the victors decided not to really root out the evil they had defeated an instead allowed it to metastasize. There may be no peaceful resolution; there is certainly no possibility of a peaceful divorce.
The time to split the country was when the Confederacy seceded. We should have just let them go, but that would have meant ignoring a human-rights atrocity, and in any case it would have resulted in a shared border with a belligerent enemy nation and ultimately with a failed state. It's definitely too late now.
It is the historical task of our species to abolish slavery. In every generation we've got to reeducate ourselves about its evils.
