What is something you consider important enough to go to war over?
When you go to a restaurant and order a Deep Eddy's vodka tonic and they return with a brown-colored drink. I question it, and they say it is Deep Eddy's sweet-tea flavored vodka. Well, I tried it, handed it to the server and said, "Now THIS is the shit that should be in Leviticus."
Genocide type situation. Hitler killing Jews, the Czech conflict etc.
