I've been blessed by doing classic plays on Broadway, which was one of my great dreams forever.

We just say there are five, you know, racial groups in the US. I say that these folks are what we call a sixth American. There's something different. They are somebody who - they don't exist in any particular racial category, so they all feel it and they kind of congregate to each other.

We studied a mosque, and this is when we were at Notre Dame, and in this mosque they had people from a variety of countries, most of them immigrants. In some of the countries, when you go into a mosque you remove your shoes. To not do so could be punishable even by death in that nation. In other countries, it would be a great offense to remove their shoes when they come into the mosque, a sign of disrespect.

It happens a little bit more in the West, where there's more fluid - where everybody's originally from somewhere else. So they have a little bit more permission to do it. It happens the least, at the individual level at least, in the South, because the South has very strong, you know, set up black churches and white churches and a long history of that, and so it's a bigger social cost.

So it may be a language that separates you - again, social networks. But second-generation Asian and Hispanics, second, and third and fourth and so on, they are much more likely to be in integrated churches than are blacks or whites.

I think whites are used to being in power, so when whites think we ought to have integrated churches they think, "People ought to come to our church. What can we do to get them to come?"

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.
