Oh come on do people seriously believe boater kulaks are going to step foot outside of their lifted f-150s to fight a bloody civil war? These types that vow violence for a trump loss can't stand summer without ac let alone living in the pocconos eating spam and field dressing gunshot wounds.
I don't expect this will be an actual war, more of a mass civil unrest. I certainly wouldn't dismiss the possibility of this happening as the material conditions in US continue to erode.
Just because they won't personally fight doesn't mean they won't support the conscription of a bunch of young men to fight for them. It's not as if most confederate soldiers in the US civil war were slave owners.
