Oh dear. So, a woman said something unsavory, because there was a cause she could latch onto and suck dry, like a mosquito that feeds on excuses (really, I think people do this to make up for their lack of skill)? So, if someone calls you (well, I guess, not the OP, since the event he described didn't even happen to him) gay as an attempt to insult you, would this topic be "Should Homosexuality and Gaming Mix?"? Because something exists and has been used as a way to demean someone else should have no bearing on its relation to anything.
OT: Um, huh? Should any social or political movement and gaming mix (I mean, content-wise we'd lose a lot of great stories, but if it's really that bad...)? Why specifically feminism? This strikes me as more of a question as to whether or not women should have any opinions in relation to gaming, which is actually impossible to prevent (people will form opinions on something unless they do not know it exists). So, in reality, it would be: Should women be able to express their opinions on things? Should men be able to express opinions about women that differ from an established norm? To which, I must ask: Should anyone be allowed to express any opinion that differs from an established norm?

I feel like this is an issue of "what is the correct way to live life?". For years, people dismissed gaming as a hobby for small children, despite the fact that gaming has never been solely a child's activity. Heck, I still have to watch what I say around some people, because they'll still laugh at me and say things like, "Really? You still play games?" My parents even just barely tolerate it, but don't miss any opportunity to keep me well informed of every other "more worthy" activity I could be pursuing. And I don't even live at home anymore.
Gamers have a history of being told how silly they were, and gamers have mostly been male. So, I understand why, when some females want to advocate for more games they can relate to, it sounds like someone just telling male gamers how their current forms of enjoyment are incorrect (and thus they are living their lives incorrectly... again...).
All I would say is look past the knee-jerk reaction. Those who are advocating for more interesting female characters want what every gamer wants: better games. They're simply asking for more variety in stories and art design, not for the existing stories to be re-written. No one wants to tell you the things you enjoy are wrong. They just want more things they enjoy, too. And maybe, if you gave those things a chance, you might find you enjoy them as well. Or not.
