"Is the one who said he slept with your mother"
But, in seriousness, I really oppose the idea of getting banned in every single online game, just because you said something somebody did not like. I find that it would be yet another step into people being controlled and brainwashed. Sure, nobody may like to be called fat, gay, slut, whathaveyou, but does it hurt anybody? Let me answer that for you, not in any way, shape, or form. The exceptions have to be threats of violence, like "I'm going to find you and murder your mother", because then you could actually hurt somebody. It makes no difference to me if this was said to or by a woman or a man.
I have a "Girl Gamer" friend and she has been called certain names and teased quite a bit as we played. Now, she doesn't mind and neither do I, but the problem is that people have a stereotypical bias that they have set in stone in their minds. No gender or race is superior, as much as some would argue and the quicker we can get over this stupid hurdle made by ourselves for the sole purpose to inflict self-affliction, the better we become as a society in general.
