Incorrect. Unlike many around here I have never said that states did not have the right to secede, and I would ask you to point out where you think I did. What I have always said, and have never wavered from, is that states do not have the right to secede unilaterally. Such a power is denied them by the Constitution, including the 10th Amendment, and that is where the southern rebellion fell afoul of the law. The Constitution applies to all states, not just the seceding ones, and protects the rights and interests of all states, not just the seceding ones. And this fact was recognized by the Supreme Court in their Texas v White decision.
The fact that southern supporters believe that the Constitution only applies to states wanting to leave is something I can never understand.
We have argued about your unilateral theory before and never convinced each other. You insert unwritten restrictions into the Constitution, and I don't.
