WASHINGTON

You wouldn’t know it to look at me, but I go running several times a week. My favorite route, because it’s so flat, is from the Lincoln Memorial to the U.S. Capitol and back. I was there last Saturday and found myself plodding through tens of thousands of anti-government “tea party” protesters.

They were carrying “Don’t Tread on Me” flags, “End the Fed” placards and signs condemning big government, Barack Obama, socialist health care and various elite institutions.

Then, as I got to where the Smithsonian museums start, I came across another rally, the Black Family Reunion Celebration. Several thousand people had gathered to celebrate African-American culture. I noticed that the mostly white tea party protesters were mingling in with the mostly black family reunion celebrants. The tea party people were buying lunch from the family reunion food stands. They had joined the audience of a rap concert.

Because sociology is more important than fitness, I stopped to watch the interaction. These two groups were from opposite ends of the political and cultural spectrum. They’d both been energized by eloquent speakers. Yet I couldn’t discern any tension between them. It was just different groups of people milling about like at any park or sports arena.
