Charlie Sykes has basically spent the week on his podcasts doing warnings about Civil War. I think we are in a lot of danger in this country. The 19th Century version isn't going to happen. What will happen will look like "The Troubles" in Northern Ireland.
This happens every time there is a Democrat in the White House but the FBI has been able to pierce the balloon most times previous before real danger occurred. The existence of an unfettered communications infrastructure, out-of-control political storms are gaining strength like wildfire.
Be safe. Your racist uncle is probably not the problem but the idiot cousin might be.
