Are we in a cold civil war?
Yes we are. It is a culture war for the survival of our civilization, and it has been going on for quite some time now.
It is much bigger than a civil war. WW3!
The hot version of that one is coming. When the allegorical second horseman of the Apocalypse saunters in "to take peace from the earth, that they should kill one another." In less than two decades? Closer? It will be within our hypothetical lifetime.
