Wrong 4 counts
1) Even the states that seceded would disagree in that in returning
Texas v White 1869 conclude?
White, 74 U.S. 700 (1868) States do not have the right to unilaterally secede from the United States, so the Confederate states during the Civil War always remained part of the nation. so if a current Southern State were to have your view we could say "But you know about the Court ruling that you agreed to already.
2) The Founders , the great majority, didn't even use those categories. They said they were living up to the English law and the king had repudiated it.
3) The situation of Loyalists during the American Revolution left them free to leave but the Union-supporters under secession lost all Federal protection. Lincoln was clear on that,whatever Southern Sates did they could not force support from the members of those states who had never had a say in secession and didn't want it anyway.
4) "right to secede' can never be independent of circumstances. As I pointed out in Texas v White 1869, if you are now a member of a society that is based on you not having that right, you can't manufacture it !!!! Let's say you once did have the right, you can't have it now knowing that you agreed to be a citizen of a country that now explicitly makes it treason.
