The topic is taboo ... yet it divides Cleveland right down the middle. When the four-letter word is mentioned, people cringe. Can we talk about race? Beverly Daniel Tatum, president of Spelman College, believes it's time for just that sort of conversation. She joins us to discuss her new book, the effect of racial stereotypes on achievement, and the silence that prevents interracial friendship. How does a town like Cleveland come together? We'll explore these issues and more Friday morning at nine on the Sound of Ideas.
