But the Confederacy was inherently created to and was almost entirely about preserving slavery and killing US soldiers to do so.
I don't agree. In the first place, the civil war was not really a civil war it was a war against succession from the union for economic tariff reasons. Lincoln was ambivalent about slavery other than the sympathy that it helped his cause. If George Bush would have been president at that time, he would have told us "we were spreading democracy!" But Lincoln used the slavery card instead to spread his cause. Since he knew black slavery was going out of style anyway. This is more than obvious when you consider every other country (at the time) having slavery got rid of the practice even though they had no war of succession like the US did. Furthermore Lincoln wanted to ship all the black southern slaves back to Africa after the civil war and would have done so had he not been assassinated. That does not sound like someone coddling black people to me. Should we tear down or put Lincolns statue in a museum as well?
There were a lot of Americans killed during this conflict. It just was not really about slavery. It was about money.
Wrong. According to the founders of the succession themselves:
This part is copied from the State of Texas:
“Texas abandoned her separate national existence and consented to become one of the Confederated Union to promote her welfare, insure domestic tranquility and secure more substantially the blessings of peace and liberty to her people. She was received into the confederacy with her own constitution, under the guarantee of the federal constitution and the compact of annexation, that she should enjoy these blessings. She was received as a commonwealth holding, maintaining and protecting the institution known as negro slavery-- the servitude of the African to the white race within her limits-- a relation that had existed from the first settlement of her wilderness by the white race, and which her people intended should exist in all future time. Her institutions and geographical position established the strongest ties between her and other slave-holding States of the confederacy. Those ties have been strengthened by association. But what has been the course of the government of the United States, and of the people and authorities of the non-slave-holding States, since our connection with them?
The controlling majority of the Federal Government, under various pretences and disguises, has so administered the same as to exclude the citizens of the Southern States, unless under odious and unconstitutional restrictions, from all the immense territory owned in common by all the States on the Pacific Ocean, for the avowed purpose of acquiring sufficient power in the common government to use it as a means of destroying the institutions of Texas and her sister slaveholding States.
By the disloyalty of the Northern States and their citizens and the imbecility of the Federal Government, infamous combinations of incendiaries and outlaws have been permitted in those States and the common territory of Kansas to trample upon the federal laws, to war upon the lives and property of Southern citizens in that territory, and finally, by violence and mob law, to usurp the possession of the same as exclusively the property of the Northern States.
The Federal Government, while but partially under the control of these our unnatural and sectional enemies, has for years almost entirely failed to protect the lives and property of the people of Texas against the Indian savages on our border, and more recently against the murderous forays of banditti from the neighboring territory of Mexico; and when our State government has expended large amounts for such purpose, the Federal Government has refuse reimbursement therefor, thus rendering our condition more insecure and harassing than it was during the existence of the Republic of Texas.
These and other wrongs we have patiently borne in the vain hope that a returning sense of justice and humanity would induce a different course of administration.”
The South attempted succession because they wanted to keep slaves.
