Okay. So. I don't think that anyone is pushing back against the idea that you can't play a racist or a bigot or any other kind of character with some kind of prejudice. You see it plenty on WoD games because real world prejudices still exist. It happens. Hell, I've played a characters like that in the past.
And there's a difference between random players not liking each other and eventually making snide comments and snipes at each other to jumping right away to the idea that anyone is saying that everyone must be PC so we don't trigger the snowflakes. From what I've read, I haven't seen that.
You have two extremes here going on. Neither of which anyone was advocating for. Allowing characters to act like obstinate dicks IC? Whatever. Happens on plenty of games and it's never been an issue. From what I read, and maybe I'm wrong, it's when there's no OOC structure to discipline those players that take that freedom too far. Because there should be limits. There have to be limits.
The whole idea of 'everything is allowed' is ideal in theory. But humans are pieces of shit who will take every mile they can for every inch their allowed.
No, no game should be PC-world where everything is nice and any bad language is treated with draconian authoritarianism. But no oversight with nothing being seen as negative is just as bad.
There needs to be a middle ground, and this litmus test to say 'if it's worse than Trump' I'm not sure is the best measure.
