So in the space of a few hours you have gone for vague speculation that one particular comment she allowed might possibly have got her fired, to it being a hard fact that can be used to make your argument.
She was shut down in the middle of the AMA - In the middle of a fucking sentence, FCOL - see here. I kinda doubt it had anything to do with her job performance.
Kinda like how all the "facts" GamerGate was based on were actually just innuendo and outright lies, but somehow became fact in the minds of it supporters.
GG wanted ethics in gaming - when they got it they shut up. That's about all that's needed to show that they didn't give a flying tootsie roll about women in gaming.
