Somebody earlier in the thread mentioned Anita Sarkeesian, so let's use her as an example here. Nobody (at least nobody who isn't trolling) criticizes Anita for being a feminist. The reason so many gamers have a problem with her isn't the fact that she's a woman, it's not even the fact that she's a feminist. It's because she deliberately misrepresents games and says things that are blatantly untrue about them to push her ideological agenda. Then, when people accuse her of doing that, she tries to shut down the conversation by saying that they're persecuting her for her gender. You see it time and again, any and every criticism leveled against her, no matter how valid is labelled as misogyny, if not by her, then by her legion of defenders. I think being against that kind of behavior is very valid.
This is not the real reason she has legions of defenders. The real reason is sympathy against the extreme behavior of her critics.

This is countered by increasing the hate against her, via pages like this:

This sympathy of Anita and fear of Gamergate is summarized by Felicia Day's response:

Which was of course followed by attacks on her (and she might be my favorite female internet celebrity

This post displays the goals of Gamergate, which are quite attractive on the face of it:

But how can pursuing journalistic integrity by means of terrifying women possibly be a good thing? Even if they find flaws, how many people are they willing to terrify in the process? Their de facto censorship of opponents via terror threats undercuts any possible message of problematic journalism, and is a far greater issue than the one they are attempting to solve.
Back to feminism backlash though, let's consider the effect of practice on the mind.
When we practice sports, or debate, or mathematics, or Civilization, we are in fact training our minds to be able to undertake such activities more easily. It takes less decision-making because we have already made such decisions in the past, and we can immediately recognize a new problem as an old problem repeated, and take the same steps. We actually have to think less, and the solutions are ingrained inside our heads to solve new problems that are similar to old problems.
I claim that these Gamergate trolls have practiced woman-hating, and use this same process vs any female critic that they find online.
