So what sort of person "picks up a gun" (and that is an euphemism for using gun violence) simply because they (and usually its not as an individual but simply as a term applied to a group they are part of that has fascist views) are called a name that they don't like (yet if it wasn't an outsider calling them that they might proudly accept it)?
They were already prepared to "pick up a gun", and simply need an excuse.
BTW the answer to my question is a cowardly bully, bolstered by hanging with like-minded individuals (group "courage").
