I can see, particularly after reading through this thread, how some of Chait's specific examples may be flawed, but there's definitely truth to the overall premise of the article. The de Boer piece linked in the OP shows some heartbreaking specific examples of that.
It's something I've been noticing on GAF more, and it absolutely suffocates certain threads. One recent example I noticed was the response to
this post by Dragonborn in the recent Anita Sarkeesian thread on Gaming side. It's not a good post, but the pile-on in response jumps almost instantly to
trying to
lump him
in with a group that can easily be dismissed. It's not the only example in the thread.
Something like that shouldn't necessarily be a moddable offense, and goodness knows that Anita threads are awash with disingenuous arguments that make it hard to pick out someone who's just ignorant from a troll. But I'm sick of getting outraged at people for being wrong about small things. I don't have the energy for it. I don't like seeing disagreements that could lead to constructive dialogue drowned with negativity and sniping at people's hidden intentions.
If people aren't even given the chance to have a good faith argument where they express points that others might disagree with (points that might be wrong, even) before getting dogpiled, there's no opportunity for growth.
I don't really see it. I'll expand on this, but in light of Pepboy and Oddmorsel's comments just above (when I started writing this, at least) I think some setup is useful.
So, a common reaction to Chait's piece on the more liberal parts of the internet is that really he's just unhappy that people are allowed to criticize him, to call him out when he says something stupid, and so on. Chait's going to read these criticisms as being quite unfair - he understands himself to be in favor of (more-or-less) content neutral norms for speech that promote rational discourse, etc., etc., and
of course he's okay with (non-harassing, threatening, etc.) calling out and even some mockery. Chait'll say it's a problem, though, when calling out and mockery end up
replacing reasonable discussion, especially when they're used so as to prevent people from speaking up at all.
Where this gets a little tricky is that people disagree about what "reasonable discussion" looks like. If someone says something really stupid or rude or whatever, nobody thinks they have much
right to be reasonably engaged. Chait would agree that if Hannah Rosin had instead written a piece about how Muslim anchor babies are going to have overthrown the US government and imposed sharia law by 2020, a reaction consisting mostly of mocking tweets would be pretty appropriate.
Now, we don't all agree precisely on what's reasonable, but probably it's a good idea to try to be humble in making this determination. Maybe we're wrong. And certainly we'd like others to extend us the same courtesy. I like to think that I'm pretty charitable when it comes to this sort of thing. I spend a lot of time talking to people I disagree with about things we disagree on, where actually we probably each think the other's view is monstrous, and these conversations are enjoyable and respectful and all that good stuff, and we leave each thinking the other is intelligent and in-some-sense well-meaning. This is all some throat-clearing on the way to saying that sometimes we do get to draw a line and say that some contribution is really kind of silly, and when even I don't see the value in someone's speech you're going to have a hard time convincing anyone even broadly sympathetic to my politics that it's not deserving of mockery.
Moving on to the actual complaint: I think dogpiling on gaf is a problem. I think lots of posters are too quick to conclude the worst about other posters. I think lots of posters, including ones I basically agree with on the issues, spend too much time just trying to disrespect people who disagree with them and are a lot more interested in arguing than in discussing.
That said, I don't see the value in the linked post. In a lot of earlier Sarkeesian threads that sort of post would have gotten someone banned, and when I saw that in the ban record I'd have nodded and gone on with my day without a second thought. What we've got here is someone coming into a thread about the harassment received by a particular woman only in order to say that they don't like the woman in question. That's it. There's some boilerplate afterwards aimed at preventing the sort of reaction the post ended up getting, but that's obviously not the meat of the post. This poster's substantive contribution to the conversation was that Anita Sarkeesian "just kind of feels fake", that she's not a ""real" gamer" (scare quotes in original). And this is in a context (which I'm pretty sure this poster was well aware of) of many, many people expressing basically this opinion about the same woman in lots of other threads where individual people's opinions of the woman weren't really the topic. If the posts in reply to this post are lazy or uncharitable, how much worse is the post itself? If the response is a dogpile, unfairly judging the poster, the post itself is part of a
mountain of the same off-topic, uninteresting, lazy, and poorly-expressed judgment about someone the poster really knows very little about. This is not the sort of speech that gives rise to "constructive dialogue" and "good faith discussions".
I want to end by suggesting that if you think that "PC culture" is some huge problem, if you think that valuable speech is being chilled, it really weakens your case when you rally around examples like this. The principled rallying around even really silly speech is fine to rile up people who already agree with you, but what you want is for reasonable people who don't see what the problem is to look at your examples and think to themselves "oh God what have we wrought?". If the case against "PC culture" is that posts like the one linked aren't treated respectfully, it's really easy for people to respond in the way that so much of the internet has responded to Chait. "It was a bad post, and what you don't like is just that people mock silly, value-less speech coming from that perspective in exactly the way that you would mock silly, value-less speech coming from others". There's a reason that the people who want to argue that Chait just doesn't like being criticized focus on the bits where he complains about prominent writers being the victims of hashtag mockery for saying that the patriarchy is dead or where he kind of seems to be upset about the existence of a conversation about microaggressions or trigger warnings. There's a reason that Chait himself spends a lot of time on the much more concerning stuff, like the anti-abortion protester or the student satirist, but he ends up having to move on to noticeably weaker examples because it's very hard to argue that we've got a widespread problem otherwise.
