Eh, I don't know. I've defintely met a lot of women who seek out male attention via gaming. Played WoW with one back when I was into that, and she made me ashamed of my gender. I think my eyes constantly locked into the "rolled" position. Lady, getting a bunch of nerds excited about you does not make you fucking Alison Brie, calm down.
But on the other hand, I think people are really quick to jump to this conclusion with girls. Again, when I played WoW, I played a male character and was a pretty well regarded tank, and I'd constantly get shocked silence or "WHAT, YOU'RE A GIRL" everytime I got on vent. Eventually you start to anticipate the question and feel obligated to just get it out there quickly without also sounding like a dick.
Also, I do think there are a lot of girls who are a little bit ashamed of their hobby, so they try to make it a sexy part of their identity rather than feel they're failing as women. My sister is like this. She loves JRPGs, shooters, and MMOs, but she's also a gorgeous and fashionable hair stylist who's big into clubbing and shows that air on MTV. Obviously, it would be better if these women felt like it's okay to be anything they want, but it's not that easy for some of them, and I don't think it's worthy of hate. The world is at fault, here.
Finally, I think a lot of women who are just girls who are gamers get accused of "Girl Gamer Syndrone" because of how other people react to THEM. Take Felicia Day, for instance. Now, I'm not a BIG fan. She's a much better writer than she is an actress, and she's nowhere near as gorgeous as she's made out to be. But I like some of her stuff and think she's a pretty cool sort of person, and I can tell she's not 100% comfortable being in the spotlight and so she covers it up with that dorky ingenue thing she has going on. I definitely would not consider her one of these gamer queens who DO, sadly, inhabit the gaming world. But because of her male fanbase, Ms. Day GETS accusations of being that person constantly, and has to deal with a lot of hate heaped onto her, especially from other women, for being who she is.
Basically: yeah, there is definitely a brand of woman who does this, and she is annoying as hell. But even she probably has her reasons, and in my opinion, judge not. It's not easy being a girl gamer, sometimes. For the women who are judging these girls (and I think it's mostly women, though there are definitely a lot of men), I think we should try and give them the benefit of the doubt. Chances are, someone out there is thinking that WE'RE the little gamer queen and resenting us, and we'd appreciate the grace.
