No, she's getting exposure because she has valid points, and partly because of the way people reacted (i.e. death threats, rape threats, etc). I've not seen any evidence of Anita insulting and antagonizing people, do you have any specific examples? Anita and other women, on the other hand, have been repeatedly harassed and threatened. I really don't understand how anyone can accuse Anita and Zoe of insulting people, when they are the ones who were targeted.
By the way, gamergate started with harassment of mostly women who were critical of sexism in gaming culture, and people attempted to change the subject to "ethics in game journalism". It's strange to me that so much anger was stirred simply because some women want more diversity in video games, and have spoken out against harassment of women by some in the gaming community.
