if he really is misogynistic and homophobic that's for sure a good enough reason to hate him. i don't know him though, nor do i watch his videos so i can't really judge.
He really isn't though, looking through most of his videos and other things I cannot find a single shred of evidence that would indicate that he's the homophobic, tribal, misogynistic pig that the SJWs say. It's really just a matter of him not condemning Gamer's Gate and thusly the Anti-GG people seem to think that he is, therefore, a tribal, homophobic, misogynistic pig that beats up hookers and violates their corpses or some stuff. Nevermind that he's also a supporter of greater representation of women and other minority groups within games, believes that there should be more equality, and rails against stuff like affirmative action, which in and of itself is a tribal or loveist system.
But that's none of my business.
