I don't think the riots derailed the civil rights movement.

In the old days, you lived in one neighborhood, you knew all your neighbors and your daughter married the guy next door. That was social and economic progress. That model is gone now. We also had a world order that was fraught but fairly stable.

We have to stop making excuses. One of the things that I'm careful to show is the horrendous effects of institutional and structural racism, but in the end, you can't wait for white man or a Black man to come riding in on a white horse to save you. We have to save ourselves, and that's the lesson of "The African Americans."

My goal is to get everybody in America to do their family tree.

I have no plans to slow down.

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. Well, guess what? 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! This brother was a conquistador who came with Ponce de Leon. He was looking for the Fountain of Youth just like the white people were.

The first slave to read and write was the first to run away.
