Also, I tend to think of insult as verbal in nature, whether lies or slander or the simple old "yo mama is so ugly..." jokes. I guess it also means any action on property that could be insulting. Say somebody sprayed graffiti on Church a wall. That could be an insult. (I lean toward outrage though LOL).
