I could honestly not care less what you and the rest of the state of Mississippi choose to celebrate. But be honest about it. By far the single most important reason for the southern rebellion was defense of the institution of slavery, your claims to the contrary notwithstanding.
Oh stop that.
First of all, the WBTS was not a "Southern rebellion."
It was a legitimate cause: that being the right of
individual states to secede from an overreaching, all
too powerful union. Try thinking in terms of today's
monstrosity in Washington, D.C. and the abomination
known as Roe V Wade. There's a state's issue if there
ever was one.
What the Yankees did to the Constitution in 1865,
is the root of the evil which encompasses us today.
Slavery was ugly, it was wrong, but it also wrong
to insist that slavery was the issue that started the WBTS.
By far the most important reason for secession (it wasn't "rebellion", and you have very good reason to know it, having had it stuffed down your throat by better expositors than I) was the South itself.
Dying on your feet better than living on your knees -- and all that. The casualty figures show how many Southerners believed that. Your side, by contrast, fought a war to put others on their knees. Deny it -- can you?
You keep losing these arguments, and yet you keep wrapping yourself in your teleological council-blanket and coming back for more. Slothful induction, thou art a non sequitur.
