The anniversary of the integration of Central High in Little Rock, Arkansas marks one milestone at the end of this country's struggle to end legal segregation. The next step — real integration — is taking longer than civil rights leaders might hoped. Today, we're talking about the value of racial diversity... in your professional lives, in your personal lives, in your community. We're talking to some really interesting people — a historian who studies diversity in housing, and a teacher who edited a collection of essays about interracial friendships. (I urge you to read this essay of hers — it's beautifully written, and will definitely give you something to think about.) Talk of the Nation is a veritable rainbow of folks — black, white, Jewish (yours truly, oy), Latino, and at least two people with really great accents (Boston and Jamaican). I think it enriches my life, my relationships, and of course, unarguably, the show. It makes our editorial conversations richer, and our parties way more fun.
