Given up what exactly?
Let's put GamerGate aside and get to the real issue here.
We're dealing with someone who:
-Calls particular "gender signifiers" sexist, but insists on wearing them throughout her videos
-Claims to want open discussion, but disables comments and ratings on her videos
-Claims to want academic acceptance of her materials as part of classroom curricula, but would rather do this on the strength of public opinion rather than professional peer review
-Claims she played video games as a kid, but then later claimed she didn't really play video games
-Makes wild claims about the pervasiveness of sexist tropes in video games in wagging-finger tones, but then caps off her monologues by saying "you can enjoy them anyway", which comes across like a guy who's been making advances at you all night, and when you tell him he's not interested, he says "oh, I was just kidding".
-Makes her claims of victimhood (and ascribing them to all women, thus creating a self-perpetuating system of usefulness for herself) the frequent centerpiece of her discussions instead of solutions for solving the problems of sexism in video games
I'd like to tell you, while I shouldn't have to, I will, that I'm a gender egalitarian, I'm female, non-white, and an engineer.
I also think that both sides of the GamerGate debate are woefully off their rockers.
I wasn't offended by Dr. Matt Taylor's shirt. I wasn't scared out of STEM because of it. I HAVE experienced sexual harassment. I currently do work in an environment where there's plenty of opportunity for me to succeed and where I have not, nor have other women in my group felt threatened or abused, so I don't feel systematically oppressed.
Maybe I'm biased. Maybe I'm lucky. But the fact is, I believe that in the United States, women have far fewer problems than they used to, and the few problems they have left aren't going to be solved by jamming the gender divide into every topic, but rather globally engaging and not accusing men, and finally, just by proving you can do what they do just as well and provide products that sell.
Anita accuses, by virtue of her constant victimhood. If that's "not giving up" and "fighting the good fight", then I take personal offense because she gives a bad name to me, who does more for women - maybe locally, if not globally - day in and day out.
