For me, I find it annoying if they specify they're a girl gamer, if it's in a forum or whatever. The only reason why they would, especially in a thread title, is for attention. I don't harass anyone or belittle anyone for it, it's just annoying. I rarely actually come across girl gamers though, at least not to my knowledge. I don't care about your gender or race or sexuality, just know what you're doing and don't be an attention wore (no matter your gender)
