It's funny how they'll speak ad nauseum about the original sin of slavery against the country, the founders, and the founding documents...
But will conveniently ignore that not only was their own party complicit in slavery (which the Republicans never were, and in fact the opposite is true, the Republicans were founded with the express purpose of ending slavery), their own party seceded from the union and FOUGHT A WAR to try to preserve slavery, and even when they lost that, their own party clung to racial prejudice and oppression so fervently through segregation and Jim Crow that the federal government - the same one they denigrate for having "original sin" - had to step in and stop them.
Funny they can completely ignore all that about their very organization.
