One principle I've been fighting for that doesn't endear me to a lot of people is that black people can be just as complicated and screwed up as white people. Our motives can be just as base and violent. Suffering does not necessarily ennoble you.

We really invented the genre of tracing family trees and going back as far as we could on the paper trail. When the paper trail disappeared, we used DNA analysis. The technology was just being invented that allowed you to trace ancestry through DNA.

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.

I think that the roots of racism have always been economic, and I think people are desperate and scared. And when you're desperate and scared you scapegoat people. It exacerbates latent tendencies toward - well, toward racism or homophobia or anti-Semitism.

So many people of color who made major contributions to American history have been trapped in the purgatory of history.

If Martin Luther King came back, he'd say we need another civil rights movement built on class not race.

All historians generalize from particulars. And often, if you look at a historian's footnotes, the number of examples of specific cases is very, very small.
