You claim that in the convention they voted down a prohibition on non-slave states and claim that the constitution explicitly allows for that. Yet nowhere in the constitution is that explicit permission to be found, at least not that I can see. What clause or clauses are you referring to?
Of course a prohibition on non slaveholding states is not in the Confederate Constitution. Ill type this next part slowly for you.......
IT. WAS. VOTED. DOWN.
Get it? Rejected. Kind of like your weak repetitive arguments.
