tbh I don't know much about the modern KKK (or KKKs? There appear to be multiple independent chapters, or something along those lines. It looks like Duke was the founder of something called the KKKK, which is apparently the most KKK KKK of modern KKKs?) at all, so it's difficult for me to separate legitimate Klansmen from "omg this guy is literally KKK and also Hitler". I'm quite familiar with the 1860s-1920s incarnations of the KKK, but their modern operations seem to be close to non-existent.
