The stereotype is broken, and it's becoming far less "odd" in any way to encounter women involved in gaming or other geek passions. Soon enough, it won't be a consideration whatsoever, and that will be a great day.
I can only hope you're right. I've never found it in RTS games, but for FPSs, the attitude of some guys towards myself and my female friends can be quite.. disturbing at times. I'm glad that doesn't happen too often though.
There are quite afew girls/women online though. It just depends on the game. And I know I tend to keep quiet in case of any idiots playing (who have a vendetta against me because I'm female
), so people assume I'm a guy.
Never tried dating a gamer girl though..
