"But some of the people falling on the "anti-" side of the GamerGate are employing the same sort of "you are with us or against us" mentality. As those people get more frantic, they also damage the message they're trying to express. Silence isn't complicity. Silence might also be not letting a campaign of hate and chaos be taken seriously by not giving it a place at the table. Now, from a distance, this whole topic looks like every other politicized media conspiracy, with two sides full of extremists and a bunch of people in the middle looking disillusioned by the whole debacle."
It's like comparing those who campaign to hard on climate change are just as bad as those who campaign against it.
It doesn't look like that from a distance either. Unless you are an idiot. Again, a strange sort of false equivalency.
Silence is also complicity in the face of such blatant sexist crap. When women see the gaming industry not react strongly to this, how are they meant to feel?
In no terms is he saying that both sides have equal validity. The content of the letter should make that clear. If you're saying there's no grounds for criticism at all for some reacting to GamerGate, then I'll have to simply disagree with you. I don't believe a side is "weakened" when a sincere and valid criticism is made. That's how a movement or a response to one strengthens its position.
