Uh….no. You lost all credibility. I'm sure you were a promising child at one point.
Don't bother replying, I won't be reading.
If you had any creditability at all you would answer the question. What article of the Constitution of the United States give a state a method of leaving the United States.
You were the one that claimed such a provision was in the Constitution. Put up or shut up. Obviously you have opted for the shut up mode due to a lack of knowledge of the subject you have tried to discuss and the Constitution of the United States. I guess the validity of the old adage that “ignorance is bliss” is substantiated by you.
