There were competing KKK operations in the 1920s.
The KKK in the immediate post Civil War period was dedicated to corraling Negroes and murdering Republican politicians. The KKK in the 1920s was dedicated to supremacy over Negroes, Catholics and Jews ~ giving it an entirely different flavor.
Today's KKK is mostly irrelevant.
I would agree with that, mostly irrelevant, except when the democrat party ties them to conservatives.
