EDIT: Speaking of enforced consensus...
There's one thing in there that I've noticed in all the progressive hugbox forums - there at RPGNet, Something Awful, ResetEra, Metafilter - is that point about speaking for entire groups. Because those rules pretty explicitly state what is usually unofficial policy, which is that a single member of a minority can be said to speak for the entire group when they're offended by something. They say something's an institutional form of bigotry, you have to accept that it's true, or you're banned. But if that single member of a minority says something is
not offensive, all of a sudden they can't speak for the group, it's wrong to act like minority groups are a hivemind, etc. If they're feeling particularly feisty, that minority member has internalised bigotry.
So, for example, black people aren't a monolithic group. Except when one of them says they're offended, suddenly you've been racist to every black person worldwide. But if another black person disagrees with that first one, they're only speaking for themselves and not representative of black people as a whole. And woe betide you if you
aren't black and question whether it's as bad as that single black person says.
Not only does it make these forums very vulnerable to the heckler's veto, where only a couple of people loudly offended about everything can force a topic to be entirely about their perspectives. But they also leave themselves open to people socking wildly so as to give their opinion some weight. Because if one black person says something is racist but the other dozen black members of the forum disagree, then they
might allow the possibility that it's only that one person who has a problem. But as soon as that person has even one other poster backing them up, then it's settled - whatever they're complaining about is bad and must be considered bad by everyone.
Of course, it also encourages people to lie about their identities, but that's a given, really. I've seen numerous people in those kinds of forums act like there's never a benefit to being, say, trans in any situation, when it's obvious in lefty hugbox forums that trans posters get a lot more leeway due to their high position in the oppressive stack. Ditto with people lying about their skin colour, especially with the several rather notable examples of academic activists having to admit that they're not actually black/latino but were just lying to get ahead.
tl;dr: These places already had mod policies in place to elevate outraged voices above all others. The A-Game thread rules just codifies it so the more offended to feel, the more correct you are.
