The Klan was formed after the war. How could the non-existent Confederacy have formed it? Since the South was full of such obviously evil people—men,women,children, and even babies in the womb—and the North was full of such obviously righteous people, the North would have been better off without the South. North good,South bad. Need we know more?
The KKK was formed by veterans of the Confederacy. And I have never made any statements of calling people of the south evil so that thought is purely your own mind. As has been pointed out by Madison a State government is not neccesarily representative of its people especially when it acting with a mindset of supremacy as the democrats of the Confederacy were. For any so-called libertarian rebel they view freedom as a means of supremacy over people.
This attitude has never died within the democrat party or with libertarians either. Of course Robert KKK Byrd is considered a great Constitutionalist by the progressive movement and many libertarians as well.
The ideal held by libertarians that they can be pimps, drug dealers, sexual predetors, slave owners, etc..... and that we have no natural right to oppose these things through law is basically not an ideal of individual liberty but an ideal of individual supremacy over others. It is the Outlaw mentality of the libertarians. The libertine attitude of the libertarian that appeals to progressives and the Marxists.
Libertarians basically believe in purging goverment as a place to express morality through law. Not much different from Marx who basically preached the destruction of traditional morality as well.
