Violence is wrong no matter what. I don't care if it is men against women or vice-versa, in fact, if a man is continually abused in a relationship, it makes it a lot tougher to get help because of attitudes like Weiser's and HPs.
Sometimes telling the guy to just 'man up' doesn't work.
If the situations were reversed (same end result of 'drawing blood'), this guy would be locked up right now.
