This is why it’s important people understand the details of the civil war.
What lead to it wasn’t just “slavery” it’s that the South wanted the federal government to go into Northern states and bring back anyone that was suspected of being an escaped slave back to the South. Basically they wanted federal law enforcement to go on slave raids.
They won’t be happy with shitty laws in their own states, they want to force everyone else to follow them.
And this time the SC is on their side, and if we won’t fix that, we need to be ready for the bullshit they’ll keep pulling.
Go read Lincoln’s inaugural address.
The majority is about how he wasn’t going to federally outlaw slavery.
So yeah. The SC was proslavery, but the North wasn’t against it either until well into the war. Even then it wasn’t about doing the right thing. Wealthy Europeans knew the north would win, but also knew Southern landowners would sell on the cheap during the war.
By federally outlawing slavery, it made the agricultural land in the South drop in value.
This allowed the war to end significantly earlier.
