Taking up arms against a duly government in order to preserve an economic system based on the use of slave labor are the ideals of our Republic?
No shit. The Nazi’s kinda had the same philosophy. The Confederacy and the Nazis were leftists.
Oh BS - the states seceded and Lincoln’s Nazi regime attacked first to bring the states back in line.
Go read some history beyond what you’ve learned in your AntiFa courses in the street.
Obviously they did no such thing. They exercised their sovereign right to "resume the powers of government" they had delegated to the federal government after determining the federal government had become abusive of their rights and happiness. Obviously preservation of slavery was not their big concern because A) slavery simply was not threatened in the US and B) lest anybody think it was, the North was only too happy to offer express protection effectively forever via the Corwin Amendment....something which the original 7 seceding states turned down.
The Upper South only seceded when Lincoln chose to start a war. They had been content to remain in until that point.
