I'll agree with that, harpgirl, although I'd say "some" intead of "a lot of."

Some people also seem to need enemies, and will create them if no one volunteers. They don't have to be sure that someone meant to insult them; a hint is enough of a reason for them to be positive their (probably unsuspecting) opponent is the physical manifestation of all that is evil in the universe. In their mind, this justifies the self-righteous anger.
