As far as Daryl Davis is concerned, ending racism begins by talking to each other like civil adults. His book "Klan-destine Relationships: A Black Man's Odyssey in the Ku Klux Klan" is being re-released this spring, but you should make sure you set your DVR to your local PBS channel on February 13 when his incredible documentary airs. You can see the trailer up above.
By the way, he's not all talk -- he's directly responsible for an estimated 30 to 40 white supremacists leaving the KKK, and he's indirectly responsible for the departure of another 200. He hasn't dismantled the KKK yet, but it's a good start.
