Was thinking this one over while out with the livestock.
For me, most of my community is pretty easy going, and respectful of each other.
I would like to think we would have a community meeting at the town hall, form a lose neighbor hood watch/security/even call it a local militia where if someone is in trouble, everyone comes running. Could be the new voluntary fire fighting company.
Do random patrols to keep a Bosnia like situation from happening.
I do think people will tend to gather based off of differing aspects: Could be race, religion, socio-economic class, even politics.
Problem is, as Daisy mentioned, what if we had a situation where it did fall along political lines, and you just so happen to live in an area that is of the opposite ideology? Keep your head down? Try to make a run for an area controlled by your “kind?”
I am not of the “shoot first, ask questions later,” kind. But if I see someone beating up on my elderly neighbors, yeah, I am going to shoot.
