Except that as evidenced by this thread and about five thousand others-- people clearly do still care, and women who play games are still treated differently than men who play games. And not just "when they put themselves out there".
Also, did you seriously just make a point about gay pride? You realize Gay Pride Parades come out of a history that involves people getting beaten up for being out, right? There can be Straight Pride Parades when heterosexuals get regularly beaten, killed, denied housing or work because they like to touch the bits of the opposite gender, dude.
Much like that, the "phenomenon" of women making it clear that they are women and they are playing games comes out of a history of being told that we don't exist, or if we do we should go back into the kitchen and make sandwiches. The best way to desensitize the mainstream to something is to discuss it. Put it out there. Prove that, yes, this does exist, no, it's not going away, and there is a community that refuses to be shamed for liking something they're being told not to enjoy because they have the wrong bits.
