“under whose orders?”
I get that question. I do. I strongly suspect there will arise leaders with strong Constitutional values that will act. If so, I will follow.
Secondly, there (like the first Civil War) will be states that will align themselves with the right side. And of course, the wrong side. Fortunately for me, I live in Texas. I have no doubt that freedom loving Texans would make the right choices if ever CWII were to occur.
In Texas you likely would be in a two front war.
