There is nothing wrong with fitting stereotype. Stereotyping people and boxing them into the specific stereotype that is wrong, and seems to be very common.
Also I do like alot of stereotypical games, however I also like games like tf2 and cod4, so its easy to find correlations to stereotypes, but there usually is more to the story.
As for abuse in game, I don't talk and I am usually quite happy just quietly doing my own thing so nobody ussually knows I am a girl. When people find out for some reason I have had a couple of abusive people, a fair few shocked people, but mostly they are like "kool" and throw a grenade in my face

As far as difficulty goes, I always start on hard because I love a challenge, but really its personal preference, games are for fun and relaxation, do what you like and screw anyone who says your less worthy for it.
Also DDR is excellent fun

Edit: Mookie_Magnus I completely agree with the GGS people, they tend to be up there on my gun for list, can be very annoying.
