Instead of the civil war you’re imagining imagine this one instead.
You’re standing over a ditch filled with women and children soaked in gasoline and preparing to burn them alive. A neighboring sectarian group mortared a local playground and this is retribution.
It wasn’t supposed to be like this you think to yourself. Originally our militia was based on the ideas of liberty and the constitution. But those were the early days. Some sociopaths rose to leadership in the militia around the same time the fight became as much about food as it did freedom. You thought about getting out, but a couple of your neighbors and good friends had the same idea and were discovered by the leadership. So they were executed after being forced to watch their families being publicly raped almost to death and then dismembered alive. Unfortunately, the security needed to keep your family alive means that your fortified town is just as much of a prison as it is a “freedom base”and since you’d been acting kinda funny lately leadership decided they would put you on this detail to see if you were still a part of the group.
So there you stand on the edge of a ditch almost deafened by the screams of women and children who are going to be burned to death wether or not you light them first. But if you don’t, something similar or more horrible is going to happen to your family while you watch. Before you yourself are treated to a similar fate.
So, if civil warring stills sounds like an awesome fun time after imagining that then have at it.
