Let's look at two things real quickly: the civil rights movement in Mississippi in the Sixties and the Arab Spring starting in Tunisia and Cairo. What they had in common was people who were told, and who believed inside themselves, that they were a certain way, and the society at large believed it.

I was involved in the anti-war movement.

I was a good liberal in some sense at that point. I wanted to end a war. I wanted to support the civil rights movement.

Where's the activism? Nobody knows. And anyone who thinks they know, like Todd Gitlin, has their head up their ass. Nobody knows. The day before every revolution that's ever happened, that revolution was impossible. The day before Rosa Parks, that was impossible. The day after, it was inevitable.

My father lived with me the last five years of his life and passed away of Alzheimer's, and at that point he was saying to anyone who would listen, "We all hated the war in Vietnam." Well, it was easy to hate the war in Vietnam 40 years on.

Martin Luther King was only an activist for 13 years and every year he changed and every year he became more radical. By the end he was calling for revolution. People don't know this because they go to too many prayer breakfasts on his birthday.

What was on the agenda was school and social life and those kinds of things. So I was the middle of five kids. So I had the great advantage of being able to play up to the older kids and play down to the younger kids and I think that's part of what propelled me to become a teacher at some point in my life. But it was a comfortable childhood. It was a privileged childhood.
