An oft voiced opinion, but let me point out that with the exception of South Carolina and Georgia the 7 rebelling southern states ratified nothing. They were admitted. They were allowed to join, and only after a majority of the other states permitted them to do so through a vote in Congress. They were, in effect, created by the other states when admitted to the Union. So since they were allowed to join only with the permission of the other states then why shouldn't the other states have a say when they want to leave?
Do us a favor and quit spouting the revisionist dog crap they teach in public schools.
But by all means bring on your southron myths. They're fun to refute.
Slight of hand, Non... they petition for statehood, once granted, they are on equal footing, unless you can demonstrate that the Constitution says otherwise.
