Do you really think this is the time and place to attack a political philosophy that you disagree with?
Why not attack alcohol drinkers. poor parenting or people with tattoos? They are all just as likely to have caused this oaf's behavior.
I would say the booze had the most effect on his behaviour. When I've been drunk (many years ago in college), I wanted to curl up in a corner and go to sleep. Others react in just the opposite manner. It seems like this H-D rider was one of those. If we weren't in the middle of an election season, he could've been just as upset if you were a guy with a pony tail...or if you didn't have a pony tail and he did. The reason for the potential fight doesn't matter nearly as much as the over-consumption of booze.
