This is factually incorrect. Secession wasn't violent. It was relatively peaceful. It only became violent when the government being separated from decided to send warships to create a military confrontation.
A war they intended to win in order to preserve an economy based on the use of slave labor
And this is a lie. It implies a change from the status quo under the Union.
Nothing regarding slave labor would have been different had they remained in the Union, and so your vituperative hatred of slavery in an Independent South should be just as shrill when talking about the normal conditions of the Union.
Slavery was the normal condition of the Union at that time, so trying to whine that the "South had slavery" is a deliberate attempt to deceive the fact that the North had it too, and the entire Union would have kept it!
Hell, the mostly Northern congress even passed a constitutional amendment to keep it!
Those are the undeniable, inarguable and immutable facts.
I have denied them, and furthermore I have proven them to not even be accurate, let alone "facts."
