Well, it is the only non-fighting sport that allows fights. Seems like something liberals would not be endorsing, so I'm not quite sure what your bitch here is.
More than likely, it's your hatred of yourself is so overwhelming that you need to lash out at others for perceived transgressions in order to make yourself feel better.
I suggest doing something with your life so you can stop hating yourself so much. Just go out and accomplish one thing you can be moderately proud of and that feeling of self loathing will ease quite a bit, perhaps enough so that you can sleep at night again.
