We could argue and nitpick Chauncey DeVega's list of The 10 Most Racist Moments of the GOP Primary (So Far), but I prefer to simply recommend it, and to draw attention to the comment I posted:
South Carolina and the rest of the Old South consoles itself with the words of Jefferson Davis on Yankee tyranny, after the Emancipation Proclamation: "I am happy to be welcomed on my return to the capital of the Confederacy--the last hope, as I believe, for the perpetuation of that system of government which our forefathers founded--the asylum of the oppressed, and the home of true representative liberty...anticipating the overthrow of that government which you had inherited, you assumed to yourselves the right, as your fathers had done before you, to declare yourself independent, and nobly have you advocated the assertion which you have made...You have a cause which binds you together more firmly than your fathers were. They fought to be free from the usurpations of the British crown, but they fought against a manly foe. You fight against the offscourings of the Earth...Every crime which could characterize the course of demons has marked the course of the invader...They have come to disturb your social organization on the plea that it is a military necessity. For what are they waging war? They say to preserve the Union. Can they preserve the Union by destroying the social existence of a part of the South? Do they hope to reconstruct the Union by striking at everything which is dear to man?--by showing themselves so utterly disgraced that if the question was proposed to you whether you would combine with hyenas or Yankees, I trust every Virginian would say: 'Give me the hyenas.' "
And so they have done.
