States right’s = political power. The civil war was fought over which “powers” belonged to the Fed and which to the states.
The right to own another human being was but one of many powers the states believed had been delegated to them by the Constitution. Others being, The North subjugating the southern states to Federal “Land laws”, The national “draft” as opposed the the southern states belief that troops could only be raised thru requisisition to each of the individual states, protective tariffs and nullification, the “Tariff of Abominations, and above all the Souths belief they had the unilateral right to secede from the union.
There are plenty more.
You really don’t know much about the Civil War, do you?
Just a couple of points about your farrago of nonsense, there was no draft for the Union Army until 1863. Nor were federal land laws threatening anyone unless you speak of the inability to legally take slavery into the new states and territories. Since the South had controlled the federal Congress and government for decades (thanks to the votes not allowed the slaves} it is clear there was no oppression from the Union.
Don’t take my word for it look it up, the only prior president not from the South who opposed Slavery was John Adams.
The CW was fought for ONE reason. Slavers were terrified that Lincoln would free the slaves. The Firebrands had been itching for separation for at least 10 years and conspiring to bring it about.
Your idea of the CW is from a bad Cliff’s Notes version of history but less accurate.
The Constitution lists those powers which belong to the Feds. Any others not on that list are the powers of the States which is so stated in the Constitution.
