Pacifist

A lot of people see someone with long hair and think all people with long hair are pacifists by nature, without really knowing anything about the person they're trying to get into something with.

The guy kept talking shit to the guy who didn't want to fight him because he thought anybody who didn't want to fight was the same as a pacifist who passed on the fists.
