re: If the south seceded again,

stop. you intentionally twisted my words. stop going through life being ignorant.
nobody said it was completely based on slavery.

But hot headed southern politicians in 1860-61 chose secession, as a result of Lincoln's election, in lieu of negotiation so they could preserve slavery.

the CSA forged a constitution almost word for word as ours, except it had a provision to allow for the right to own slaves.
