Agreed, agreed.
I'll throw one particular instance that bother me greatly: as a female gamer that frequents a couple of female dominated gaming communities, I see much of:

"Boys think that because I'm a girl I play with a pink DS and I like cutesy games, well I'll tell ya: I'm a grrrl gamer I don't like cutesy stuff or pink stuff, boo Ds and boo RPGs and boo anything that might make me look feminine or like a female and I play only FPS and I PAWN YOU ALL, LITTLE BOYS, HECK YEAH H.A.L.O.-W.O.W.-R.E. I'M THE BEST AND TOUGHEST GAMER OUT THERE!".

Soo tired of that crap, who cares what you play or what your boyfriend du-jour thinks, I don't give a damn if you don't like Nintendogs, who gives a damn.
And I'm not saying that girls should stay in one mold, don't bite my neck for that, but, really, do we all need to know about all your grrrl power all the time?, I sure don't, do your own stuff and leave me alone to do my own stuff.
