>>88281049/co/ easily gets asspained about things. By now he's talked shit about, or just said "I don't personally like" about something someone really likes, and it resulted in hivemind pissy attitudes.
Oh, and he's a bit too close to /a/ and the cosplay culture, and his Lets Play was legendarily bad or something, I dunno, I didn't see it.
He loves Stephan Universe.
Also, a lot of people hate parts of his cast for reasons. Back when Nostalgia Chick was a thing she was far more opinionated and less funny than him, pissing people off. The black guy is a furry which is the traditional enemy of 4chan, and the chick is a tad annoying. He also groups up with other people that /co/ hates like Linkara and Spoony.
Plus /co/ is full of contrarians as well as sheep. So people will shit on, vehemently defend, and mass together on any opinion regardless on if they share it or not.
Oh, he made fun of Donald Trump a few times. I mean, basically all comedians have at some point in the last thirty years, but /pol/ are fucking retards who pretend they're members of all other boards like Soviet propagandists.
