I don't think these guys heard you .....
Or they're sitting there with their hands over their ears shouting, "La la la la la la I can't hear you!!"
The wide variety of arguments why Congress or the President could forbid States to leave the Union if they were unhappy, gives them the lie. They're all over the map.
Remember Non-Sequitur's amazingly Hitlerian theory that States couldn't secede, because Congress created the States, made them States by admitting them to the Union? and therefore the language of the Constitution itself about how new States would be endowed with all the powers of the original 13 States that ratified the Constitution, didn't apply to the new States?
Remember that chestnut?
