I had been hearing on-the-ground buzz that white folks were moving to places like Bend, Oregon, and Coeur d'Alene, Idaho, and St. George, Utah. That led me to discover through census data that these towns were already extremely white and they were becoming, in most cases, even whiter. Statistics could only tell me so much; in order to get to the spirit and essence of it, I had to immerse myself.

When well-qualified, upper middle-class blacks or Latinos or Asians move to predominantly white neighborhoods, there's what's called the tipping point. That tipping point is generally 15 percent; at 15 percent you begin to see white flight.

In the pioneer West Whitopias, immigration tended to be the dominant social and racial issue. In Forsyth County, Georgia, immigration is still an issue, but because you have that complicated history of the Trail of Tears and slavery and Jim Crow, the Whitopia has a different flavor.

I concede that segregation can allay social tensions immediately, but it further debilitates us in the long run.

The interesting thing about Georgia is, Atlanta is teeming with middle-class black people and black people with money - and yet there is still segregation.

If I were an immigrant Latino not born in the US, I could not have written Searching for Whitopia: An Improbably Journey to the Heart of America book. And that is because many of the Whitopians would not have been comfortable talking about their views on immigration, talking about their views on taxes. And they wouldn't have spilled to me the new script on race and poverty as they did.

I don't want to live in a monoculture of any kind. I don't want to live in a wealthy monoculture, a black monoculture. I don't want to live in an elitist, progressive monoculture.
