Violence erupts at rally. Could this be the start of the next Civil War?

When White Nationalist's have a rally in places like Charlotte, Virginia, they show up prepared to fight. Increasingly, these sorts of rally's have grown more violent. Now getting to the point where police and even the National Guard are routinely called in, in anticipation of violent events, not speeches.

I have to wonder if we are witnessing the early beginnings of the next Civil War!
