I see this in the way that sermons are preached. How would you give a Black Nationalist speech or campaign for the Republicans when you're an integrated congregation? It doesn't happen.

Humor is so culturally based that when I try to tell a joke as me being a white American, if I tell other white Americans, they'll laugh. If I tell an African American, they might not laugh. In fact, they either might not find it funny, or they might find it offensive, and I didn't mean it to be offensive. So these are the sort of little things that build up over time, just like in a marriage. You know, the little things can build up over time.

And different traditions stress different - so then there's that. I talked to an African American who says before she goes into an interracial church, she sits in her car and she listens to gospel music to get her fill, and she goes into an interracial church where they don't do gospel music, and she's ready to accept the other sorts of ways of worshipping. So there's that.

If we go into white congregations, non-whites will sometimes say it felt like worship never started. It was sort of dead and didn't feel that warmly received. But so - and there are different realities either way, and it makes it difficult for all groups to try and cross boundaries.

It's the sad fact of how race still works in our country. We find that over and over again.

We're going to see more, and we are seeing more, and I'll tell you exactly why. Not because white and black are more likely to get together. Only a third of the seven percent of congregations that are interracial are black and white.
