The real civil division is the loss of the reasonable social consensus that once united America. Today values ,practices and expectations are so different between the two main groups in America that division is already defacto. Neither side shares values, likes or respects the other and each prefers as little social interaction as possible. They even prefer living in different areas. Real organized violence against each other? Doubtful. However unified action whether it involve domestic or foreign affairs will be very rare.
Much of America’s social consensus was built on living and abiding by the ideals of freedom - self defense, self control, independence/self reliance. The liberals have now “progressed” beyond the legal and power constraints of the constitution without the consent of the people.
It’s dang scarey. With their “citizen of the world” globalist rule ideology, I knew the rubber would hit the road sooner or later. They have taken on the attitude of a ruling class - like foreigners.
American freedom and independence is an absolute opposite ideology from globalism. We had a war of independence with a globalist king one time. I guess that is where we are headed again. : (
