Cuba is like going to a whole other planet. It's so different but it's so similar to the United States, to Miami. It's like a doppelgaenger. It's the mirror image. And I have no doubt, that once Cuba becomes democratic, that it will be the favorite tourist destination for Americans.

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.

Fortunately, in President Obama, the child of an African and an American, we finally have a leader who is uniquely positioned to bridge the great reparations divide.

You can find virtually everybody black back as far as the 1870 census. Why 1870? That's when the ex-slaves first have surnames. But if you find your great-great-grandfather in 1870 and it says he's 50, that means he was born in 1820 and you're back to 1820 already. For an American that's pretty damned good, you know?

Everybody wants to have sex - you don't have to have a baby when you're 16. You don't have to do drugs. I think our Sunday schools should be turned into Black history schools and computer schools on the weekend, just like Hebrew schools for Jewish people, or my Asian friends who send their kids to schools on the weekend to learn Chinese or Korean.

We can revolutionize the attitude of inner city brown and black kids to learning. We need a civil rights movement within the African-American community.

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.
