If there was a civil war, it would end pretty quickly. It would end when people realized their prescription medications aren't going to be available because of a raging conflict. It would end quickly because it wouldn't be glorious as those that love the idea present it. It would end quickly because the people pushing for a civil war are arm chair warriors and would get tired and cranky pretty quick. It would end quickly because people would get hungry and there wouldn't be a quick supply of food for them. It would end quickly when they ran out of money - most people have little to no savings.
