Correct, I assumed others would understand I meant since the last civil war. Edited the comment to clear up my intent. Thank you.

It's still absurd. Today isn't close to what we saw during the depression or the 70s or desegregation or the Rodney King riot. Besides that, there's no plausible fault line in the military or any sort of ethnic or religious or regional fault line where two sides could form to fight each other.

I think we might have surpassed the Rodney King era but I wasn't alive then. Broadly agree with you otherwise.
