This guy is my new hero: https://www.npr.org/2017/08/20/544861933/how-one-man-convinced-200-ku-klux-klan-members-to-give-up-their-robes
A black musician decided to learn more about racism and why it is the way it is, so he talking with KKK members and interviewing them in hopes of writing a book. Turns out after just hanging out with him long enough, KKK members tended to stop being members. Including three Grand Dragon's.
The full interview is a hoot, but I haven't tracked down a proper podcast yet. I need to get a copy of this guy's book, too.
