Allowing for cognitive bias, I see nothing on the horizon that makes my scenario of America's dismantling less likely as time goes on.
I have sort of settled into seeing people as proto-citizens of new countries. It makes a lot more sense of their beliefs, attitudes and behavior.
Looking back, I begin to think how odd, if not crazy, it was and is to imagine that peoples so adversarially different from each other could ever have been considered fellow-countrymen just because they find themselves inside the same borders.
Men as opposite from each other as Jefferson and Lincoln both knew this.
