Driver....excellent points.
And it goes for fights between women/girls from high school on up. Just take a look at the real youtube girl fights, and you constantly hear the spectators chastising the girls to stop pulling hair, break them up and have them start again on their feet, etc. And good point by clark85...if you want to watch two girls fist fight toe-to-toe only, with no hair pulling or rolling over on the ground, you might as well watch two guys fight.
I realize I'm very old school, and I have absolutely nothing against women and girls standing up for themselves, and using their fists. But I also understand there are real differences between males and females and how they look, think and act. I think what turns many of us on about girls fighting is watching them fight like girls! I have no interest in watching two guys duke it out, but two girls? That's exciting and frankly, sexually stimulating....at least for me.
