That was the position of the Southern representatives to the Constitutional convention. That was the position of the Southern population up to, through, and in many cases after the Civil War was over. The whole Southern society was built on a master race concept and the ownership of other human beings. Does your condemnation extend to them as well?
My goodness, firing up that wacky wayback machine once again, I see, darkly attributing some vaguely Hitlerian concept, a century prior to the advent of Nazism.
There was no "whole southern society," as if it or anyplace else was some sort of monolith. There were entire regions of the south that did not embrace slavery.
I suggest you make the attempt to move beyond the bizarre pop history taught in public school and actually read a little. Quakers, Moravians, Republican strongholds in the Appalachians opposed to the point of actually splitting off (West Virginia) or attempting to do so (the abortive attempt to revive the Free State of Franklin) ... all that means nothing when you buy into the whole, oddly hypnotic and historicist "slave power" mythos that was handed to you on a silver platter.
You've bought into the revisionism, hook line and sinker, have demonized an entire people on that basis, and have the temerity to prattle about the "master race." Do you ever listen to yourself?
