There will be no CWII. At least not in the conventional sense. I know it is helpful for some to bluster and throw that out there. But to your point I do think there will be tipping points and civil disobedience etc but no mobilized war. There are damn few patriotic statesmen around like there were in the 1860s. No politicians are calling for a civil war. Not even one that I know of. This vote demonstrates how bad things are.
It’s like the Texas “secession” threads.
I always tell them to ping me when the first Gov, Lt Gov, SoS, Atty Gen, or member of the Legislature advocating it gets elected.
