The Klan is not and was not a religious organization. It was started as a Confederate vets. organization after the Civil War. It became violent very early on. By the 1920's it was VERY popular, but it was still an anti black, anti Jew, anti Catholic, and anti immigration organization. Do not take this from me. The "holy" book of the KKK is in the Lib. of Congress. I believe it is call the Kolan , read it for yourself and see what they have always been about.
Having been a Missouri resident for the first 34 years of my life, I can tell you that the Klan is big there. I was a police officer in the late 1980's and earlly 1990's and the Klan was a pain in my butt. I am glad to see Missouri get back at the Klan in any way they can!
