>>211572385 (OP)they were too chicken shit and conformist to articulate why there could be a civil war, because that would involve them having to spell out what factors would make the US fragment into warring factions. They could do it, but not without articulating a clear social/political framework; side X is made up of these people and believes this, side y is made up of these people and so on - now you're getting into potential Turner Diaries territory
So the US political landscape is never discussed. The civil in this movie is like a zombie plague, it just happens and makes people kill each other with no rhyme or reason.
