Louisville, Colorado, which was just voted by CNN and Money magazine as the best place to live, is a veritable Whitopia that is unaffected by the housing crisis and even the severe recession. You look at the best places to live, according to Money's 2009 list, and 9 of the 10 are Whitopias.

There is tremendous long-term harm when Americans accept ethnic and class balkanization as a de facto fixture of American life. I think that impoverishes our understanding of each other.

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.

Problem with segregation isn't that people can't live in peaceful harmony singing "Kumbaya" - although that wouldn't be bad. The problem is that many of these Whitopian communities are taking state, local, and federal resources with them.

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.

With growing and intermixed minority populations, our democracy can not work optimally unless all people are integrated as full and equal members, and I think our collective freedom requires that.

I was surprised by how forces in the community could mobilize against a community changing. There were many examples of this. In St. George, members of the Latino community proposed having a "Dixie Fiesta." The resistance to that surprised me.
