It bothers me so much that Paul Graham people thinks it's
performative. He can't imagine anyone actually, sincerely holding those beliefs, because he doesn't hold them himself. If someone is trying to modify their beliefs and then their behaviour, say, by mild self-censorship, he's got a list of insults ready for that person trying to better themselves: prig, politically correct, woke.
It's not performative. We really do believe that there are injustices and that if we can begin by changing the language, we can change the behaviour.
Just because Paul Graham can't imagine himself sincerely believing in self improvement followed by social improvement doesn't mean we don't believe it in ourselves.
