Daryl Davis, talking with Nick Van Der Kolk about his work combating racism by befriending KKK members. Emphasis mine.

Q: What about well-meaning white liberals?
A: There are a lot of those... and there are a lot of well-meaning black liberals. But you know what? Again - when all they do is sit around and preach to the choir, it does absolutely no good. If you're not a racist, it doesn't do any good for me to meet with you and sit around and talk about how bad racism is.

If you don't listen to Love + Radio... ugh.
