I dont see the need for any fuss about girl gamers...

I dont know maybe its just me, but in my online circles i have never experienced players freaking out like this if they find out a girl is playing with.
Yes some ppl are idiots and immature morons - maybe even more so in the male online gaming community, because you can just do what the f#(& you want and nobody knows you, but you would find this in real life as well.
Just dont bother with such people. Seriously.
(At least in WOW you can just hit 'ignore' and Bob's your uncle.)

So yes, i dont care who is owning who in a game of COD/GOW/TF2, if you're good, you're good. It also means that if you are the one being owned, you should actually take notes on how to play better and stop making excuses, or insulting the other players (male OR female).
