The most "anti-PC" people in the US have their own jargon and codewords and "safe spaces" with all the same restrictions, just turned on their heads. For instance, there are very few places you could go where people would tell you to your face that black lives don't matter, but a much larger set of places where it wouldn't be "PC" to wear a Black Lives Matter shirt.
There's also something called 'decompression therapy' that supposedly helped youths with psychopathy become less psychopathic.
The theory as I understand it goes like this: Everyone has a 'sphere of empathy', they empathize with those inside it but not outside. To a psychopath that boundary is their own skin, to a vegetarian it includes all animals, to a pescatarian all land animals... you get the idea. What makes people's sphere of empathy expand is feeling safe and empathized with, it allows them to risk the vulnerability of empathizing with someone who might betray them. But it's like voluntarily relaxing a muscle - the process is slow, and while the right pressure can help the problem point relax, too much pressure will make it tense up more.
e.g. ESPN pulling veteran announcer Robert Lee off a University of Virginia football game because his name is too close to Robert E. Lee, the Confederate general is an example of political correctness in action, and that has nothing to do with treating people fairly (certainly the announcer wasn't treated fairly in this through no fault of his own), but to prevent the risk that someone might get offended;
Censoring Huckleberry Finn (for having the n-word in it, despite being a great anti-racist novel of the time) done at some institutions was another example of political correctness - again, there's nothing in the act about treating people fairly, it's simply a fight against "taboo" words or thought, and that is pretty Stalinist in some aspects.
Pretty sure that the announcer himself asked to be moved to another game.
