I posted something when I was new do DU saying I was concerned about a second civil war.

58. In the days BT (Before Trump), I would have said no. BT I believed that CivilWarI settled the issue

...of whether states could secede, among other things.

Four years of Trump has taught me to see the divisions in our society differently. There are people for whom the Civil War never, ever ended, and they are not confined to the former slave states. They are ignorant — some are stupid, to be sure, but even the intelligent are ignorant, thanks to the elimination of Civics classes from our high schools. Dropping Civics is like dropping English and then wondering why the next generation can’t spell or even read well.

General Ulysses S Grant said that the next civil war would not be between regions or states, but between intelligent, educated patriots and...those who aren’t. (Someone’s been posting a good meme on that one; very apropos just now)

Right now, I think we are in a Cold Civil War. I really do.
