He is not that far from the truth, though. I mean, i can say some of them are cool, but most of them came through the internet in that 2014-2016 era where everyone got hyperfixated on combating this sort of stupid "cultural war" with agressive shitposting, making every topic tangential to some sort of political theme, in some cases even with blatant ideological goals behind.
And the people influenced by that era are in general very annoying, and cancerous to any kind of interesting/fun discussion.
