1. If the left starts their war, I expect the absence of borders/separation to lead to a situation like Bosnia. As with that country, enclaves neighborhoods, towns, counties, and states can alternate on which faction dominates. That is a formula for ugly. I hope America's enemies will take that into account as they decide whether to force a civil war.
2. Many of us wear uniforms, whether or not they are issued. Many Obama-voters wear their pants halfway down, dress like Pajama Boy, or otherwise communicate their treason. Most decent people dress like they have jobs and work hard. The absence of uniforms will not interfere with forming reasonable suspicions on each person's leanings.
3. What to do about neighbors is a tough question. I have a neighborhood voter registration map that shows Obamavoters and decent people. It's nice to know which people I'm likely to deal with are parasites.
4. The military will be split but mostly patriotic. That will be a source of chaos or order, possibly exploited by liberal petty tyrants who will try to deceive the military. I will not trust emerging "conservative" leaders.
5. All criminals are criminals and are the enemy of decent people. It's our responsibility to keep our neighborhoods safe.
I believe it will start when we reach our Greece moment and have forced austerity upon the gibsmedat crowd and forces a haircut upon us savers and responsible people. Yes, I’ll be very angry.
