I am very proud that they stood up for states rights, whether you or I or anyone else like or dislikes the reason given for leaving is no concern of yours or mine but only of the citizens of that state. To think otherwise makes you a fascist. Are you a fascist?
The reason for leaving the Union is of consequence. And the only reason provided in the “Declaration of the Immediate Causes Which Induce and Justify the Secession of South Carolina from the Federal Union” was that their ability to own humans as slaves was threatened by the election of Lincoln.
And they made that declaration on Christmas Eve.
