If I'm sexist to say that I'd never hit a woman, but would hit a man, then by golly, I'm sexist.
I wouldn't go so far as never hitting a woman, but I'm certainly less likely to. Perhaps that has to do with me being slightly awkward amongst females. (Hey, I'm 15, what do you expect? =P )
So I guess I am sexist. I try not to be, and I like to think I usually (not neccessarily always) succeed in that. =)
This is sort of off topic, but I've noticed something interesting over the last couple of years. I used not to be worried about appearing racist, so I didn't appear racist. Nowadays, I've become more aware of racism (and discrimination in general), so I almost instictively try to avoid being racist. Which makes me notice what race people are a lot more than I used to... which, arguably, is the first step on the way to racism. Weird how these things happen. =\
By nature I don't try to compete with females.
Me neither. It never seems to get you anywhere. =P
That's based on my observations on typical tendencies, anyway. It's not that women are any different than men regarding physical combat, but rather that they don't normally want to get involved in physical combat (aside from spur-of-the-moment rage, like throwing something at someone who really infuriates them).
I'll explain with an example: in a study, there were two games -- one competitive and one non-competitive -- and three test groups -- an all-male, an all-female, and a mixed. In the competitive game, the all female group and the mixed group were seemingly reluctant to play, but the male group was enthusiastic. In the non-competitive game, the female and mixed groups enjoyed themselves, while the male group attempted to find ways to compete regardless (eg. "Ha, look at this! I'm getting a better score than you!"). While I don't have evidence or a link to back this up, I did see it on the news. Not that anyone can completely trust the news anyway, but I tend to think of that particular channel as reasonably accurate and unbiased.

The whole point is sort of moot, though, since I'd only use violence as a defence. I'm a diplomatic person. In the case of females, however, I'd never use violence aside from any actions necessary to prevent injury to myself, like grabbing hands, pushing away, etc.
