Judging groups on their worst 'associates' is a bad idea. It's like judging a population because of their serial killers.
A better analogy would be judging a religion because of hateful extremists. Both sides have their asshats, it just seems that most of the public face of anti-gamer gate is a bunch of them.
Anita makes me raise my eyebrow, her arguments seem extremely biased and agenda filled and I don't mean for pushing for equality for women representation in video games.
I'm not so sure about Brianna since I don't follow it that well. She created a game with hypersexualised female characters. (if she's lambasted people for sexualised female characters then she's a hypocrite)
Arthur Chu is ... how do you say it? A prime example of someone who likes screaming until he gets his way. If you look at his actions on Twitter in regards to the gamergate meet up.
Then on the GamerGate side we have Christina Hoff Sommers who's been sent death threats by 'feminists' and harrassed when her husband died. Totalbiscuit initially stayed neutral until everyone started jumping on him for not taking a side and he was slowly pushed towards pro Gamergate. Another youtuber who was doing both sides of the conflict got blacklisted from anti-GamerGate supporters because he was apparently supporting harassment by allowing pro-GamerGate people on his show to deliver his side of the story.
Saying that the other side is perfectly clean is... just blind and ignorant. The other side is kinda worse since the public faces don't allow discussion. But both sides do the whole death threat, harassment thing.
It's essentially feminists and gamers VS neo-feminists and gaming media.
