Big whoop. I play P&P RPG's and some people play females.. good for them some of them are druids too. Heck some of the are Lawful Evil. This doesn't mean they are evil bastards, they simple chose to be evil this game. Play the game ignore the person, if you become friends then you can know the truth. If I played EQ, which I don't, but if I did, I would be making a female character right now to fuck with you guys.
Its just a game. and Yeah in an FPS the chicks are generally smaller, and thus harder to hit.
