***Sorry, but the South seceded because of slavery.***
But not all the slave states seceded. Delaware, Maryland, Kentucky, Missourin Virginia broke apart, the western part stayed in the Union but still a slave state stayed in the Union. True, three were compelled to stay by Union troops there.
Slavery was still legal in these states till eight months after the end of the Civil War in 1865.
Maryland banned slavery in 1864.
Slavery would have ended with the invention of the Internal Combustion engine. Cheaper to park a tractor all winter while slaves still have to be fed, clothed and sheltered.
So another fifty or sixty or seventy years of slavery was OK with you?
Or even some kind of steam tractor maybe?
At any rate slavery hung over both South and North as a spiritual curse. God isn’t going to smile favorably on cant about freedom that is being constantly violated. Chattel slavery that inhered to future generations was not even a kind of slavery that was mentioned in the bible.
