Next Civil War?

Some people think that Americas Civil War was justified. I'm not one of them. Killing 700,000 plus citizens in the pursuit of freeing the kitchen help strikes as me as the height of foolishness. Now Arizona has passed legislation that will hopefully turn back the flow of illegal felons who come to America. I hope other states will follow. And if the U.S. government wants to stop that kind of self-defense legislation then they may get a modern civil war that is entirely justified. Anyone for enlisting in an Arizona militia?
