Please watch How To Tell People They Sound Racist - a brilliant July 21, 2008 podcast by Jay Smooth, host of WBAI's The Underground Railroad in New York City. He is a blogger at hiphopmusic.com and the creator of the video podcast ill Doctrine.
Thanks to Bil Browning at The Bilerico Project for posting it there. I totally agree with what he wrote:
This has to be one of the smartest videos I've seen on YouTube. Not only does he give good, practical advice, but it's entertaining too.
