In Ethiopia, the black people became Christians 1700 years ago, hundreds of years before Northern Europe turned to Christianity... And here, most of the saints are black.

In 1957, when I was in second grade, black children integrated Central High School in Little Rock, Arkansas. We watched it on TV. All of us watched it. I don't mean Mama and Daddy and Rocky. I mean all the colored people in America watched it, together, with one set of eyes.

There haven't been fundamental structural changes in America. There's been a very important symbolic change and that is the election of Barack Obama. But the only black people who truly live in a post-racial world in America all live in a very nice house on 1600 Pennsylvania Avenue.

I think that we need more economic-based solutions to the problems afflicting the Black community, and I think that that's a way to redefine affirmative action. I grew up with poor white people in West Virginia, and I know there's a culture of poverty. I know that I've seen white people perform exactly the same pathological forms of behavior as Black people do when they're systematically deprived, whether it's getting pregnant, doing drugs, dropping out of school, whatever we're talking about. I think that we should have affirmative action for poor white people too.

I rebel at the notion that I can't be part of other groups, that I can't construct identities through elective affinity, that race must be the most important thing about me. Is that what I want on my gravestone: Here lies an African American?

So when you do your family tree and Margaret Cho does hers, and... Wanda Sykes and John Legend... we're adding to the database that scholars can then draw from to generalize about the complexity of the American experience. And that's the contribution that family trees make to broader scholarship.

I'm a tech geek. Whenever I read about something new, I think to myself, How can I take this and make it black?
