If we are unable to head off this calamitous social destruction it will be warfare between the suburbs and the agricultural states versus the big cities, particularly on the coasts.
During the last Civil War there were many people on both sides who did not concur with the predominant values of the area in which they lived. Not just the slaves in the South but a good percentage of the southern urban population did not support slavery or the Confederate efforts to protect it. Many in the North opposed slavery but were uncomfortable freeing the slaves.
During the coming Civil War the same will be true. People like me will be living in the urban areas that will be attacked by the rural and suburban population.
As I think about this scenario, I realize that I live in ground zero. San Francisco is considered the most radical Left wing city in America even though nearby Marin, Berkeley and Santa Cruz are more extreme. Within San Francisco I live in the most perceived Lefty neighborhood. The gay Castro district.
If such an imaginary Civil War II occurs, guerrilla squads will come to the center of the Castro and start firing on people.
The most defensive act I could take would be to put on my military clothes. When I was in the Army Reserves during the hippie era we were always assured by our officers that the military would never be used to put down civil uprisings. I think that would still be true.
I know this sounds a little paranoid, maybe very paranoid, but I say it with the intent of suggesting this as a possibility not stating it as fact.
