This is Jay Smooth. Watch to the end to find out his metaphor for racism.
As an American, I have marinated in all the "isms" America has to offer. They have been baked into me by the media, the people around me, and the institutions that our country is built on. I can't take out my "isms" any more than I could take back the egg from a freshly-baked cake.
The best I can do is call my "ismic" thoughts for what are they are, as they come, ideally before those thoughts are translated into words or actions. Brush those teeth!
