While the KKK is without a doubt about racism, Its important to remember they also hated Catholics, and the Irish (just like the british) . So while you had to be white to join the hate was not limited towards only black poeple. I dont think SS was being sympathic to the clan he was just pointing out some history. The legal system of reconstruction dramatically changed the power structure to a more fair way and in attempt to revert to the status quo (unfair prewar laws and standards) KKK was formed to act in extralegal ways.
