Wasn't an insurrection, and slavery didn't need to be defended in the USA of 1860. It was legal and would have remained legal in the USA but for the war.
Destroying history is not al carte. If the CSA goes so to goes slavery and everything else.
‘It was legal and would have remained legal in the USA but for the war.’
o why did the eleven states of the confederacy secede, and why did four of those eleven issue elaborate declarations of cause specifying the retention of slavery being threatened...? I mean, if it was legal and would have remained so absent the war, what were the secessionists afraid of...?
Yep. Slavery simply was not threatened in the USA in 1860. Nobody waged a war to defend something that did not need defending. If anybody thought it did, the first thing Lincoln and the Northern dominated Congress offered was slavery effectively forever by express constitutional amendment.
