I'd consider myself to be one only in the sense that I'm not afraid of confrontations at all. I don't go out and actively seek them, but when the shit hits the fan, I'm not afraid of them at all. As a matter of fact, I'd rather go into one headfirst if the situation calls for it, rather than trying to avoid one.
I've come to find out, in my own personal experience, that people who DON'T mind a confrontation are few and far between.
