I would hardly call it "heroic" to be standing up against political correctness overreach. Everyone is against this, in fact aside from gaming it's the biggest subset of Youtube, even roping in figures as unrelated such as Pewdiepie. Some of the world's largest internet forums are dedicated to being against it. It's just not that impressive any more, and to me he comes across as just another "hey does anyone else think SJWs are bad?" type of person. He acheived fame only by a single incident in which he was recorded dissing some university students, and the typical "I identify as an attack helicopter" jokers are presumably the "young men" you're talking about.

I've seen his polemic rants on Youtube and they appear to be so mean-spirited and ignorant. He can't talk seriously about Marxism without bringing up Solzhenitsyn and confusing Communism with specifically Marxism-Leninism.

It would be better I think if he sticked to something I have heard he is good at doing - helping people out, rather than diverting into a strange strawman of someone extremely ignorant about political philosophy, though I suspect he must continue to do that in order to keep the little bit of fame he has managed to cling to since he was recorded "schooling" some (also ignorant) university students.

People aren't interested in his psychology, because the same people interested in him who weren't before are the people who'd be listening to Ben Shapiro and the philosophically ignorant, scientism-adhering side of Christoper Hitchens (poor Peter is too "normie" for them). He's not the first to so desparately cling to and place empiricism on a pedestal.
