It's less "civil war" and more "insurrection". In the sense that I don't see Californians, or indeed most Floridians, suddenly taking up arms and joining a militia.
It's more likely to play out as Jan 6 did, a riled up mob that turns violent and is squashed.
It becomes more of a police action than a civil war, and frankly, despite all the guns collected by the faithful, its not a fair fight.
Indeed the sides are so unbalanced, outside of a few skirmishes here and there, it's not a "civil war" like the last one.
