We can't split up, all too interdependent. For example, I see people on here telling the red states to fuck off to themselves. Good luck eating food.
How about military presence? Trying to split down on that is a hard stop, not even thinkable. The federal government ain't going to allow it, no matter what.
Any Southerners wanting to try again are getting stomped far faster than last time. Even then, you got armed libs like me embedded in the countryside. And yes, it's worth my life to shoot "red shirts". (And that's easy for me to say. I'm older and understood my history classes.)
