David Mamet, a left-wing icon as a great playwright, has moved right and has published a book declaring his political conversion began when he first tried to write an explicitly political play in 2004:

"“This was after the 2004 election,” he told me in an interview last month. “I’d never met a conservative. I didn’t know what a conservative was. I didn’t know much of anything."

What an honest, and honestly embarrasing admission.

I lived in New York City for 15 years. Most of the people I met had never met a conservative, other than me. My best friend used to introduce me at parties as "her conservative friend Maggie," until I finally got fed up and told her "I don't introduce you with ideological warning labels, I assume my friends know how to behave at parties."

The chief advocates for diversity live in enclaves where they never have to know those they denounce as narrow-minded, provincial and intolerant.

The profile by Andy Ferguson, "Converting Mamet" is very interesting for a number of reasons. But that leaped out for me.
