The sad truth is that the civil rights movement cannot be reborn until we identify the causes of black suffering, some of them self-inflicted. Why can't black leaders organize rallies around responsible sexuality, birth within marriage, parents reading to their children and students staying in school and doing homework?

What happened in the interim is, billions of records have been digitized. Historians and scholars have always used genealogical records to tell the story of American history. It takes months and years of research. I can't even tell you how laborious that is. You have to be somebody who has a lot of free time, like a professor who can take tenure or someone with a great deal of leisure.

The biggest surprise for me, without a doubt, was that the first black people who came to the United States weren't the 20 who arrived in Jamestown in 1619. All of us had been taught that. The first African came to Florida in 1513. And the huge shock is we know his name, Juan Garrido, and that he wasn't a slave. He was free!

But you see, our society is still trapped in this binary, black/white logic and that has had some very positive implications for our generation. It's had some very negative ones as well and one of the negative ones is that it creates enormous identity problems for people who have one black ancestor and all white ancestors for example.

My family and our neighbors and friends thought of Africa and its Africans as extensions of the stereotyped characters that we saw in movies and on television in films such as 'Tarzan' and in programs such as 'Ramar of the Jungle' and 'Sheena, Queen of the Jungle.'

I'd say imagine that you wake up one morning when you're going through a midlife crisis. You're getting divorced. Your kids won't speak to you. Their faces are covered with acne, and you have to decide why you should get out of bed. That's the career you should pick. The one that keeps you going no matter what, even if your life is falling apart. That's how I feel about my career.

You notice patterns. White guests often are mortified - that word again - when they learn their ancestors owned slaves. But I've never had a black guest who was upset to learn about white ancestry that probably involved forced sexual relations.
