I wanted a racially just society. I wanted to end wars. I wanted to end white supremacy. I wanted to create a world that was based on egalitarianism, sharing, racial justice.

I find some unity with Ron Paul.

In Cairo, these young men hanging around in the street, we're told these guys are lazy, they're uneducated, they don't care, they don't have any political instincts - just like the working class in America, apparently - and then suddenly what the hell happened? What was that? They changed the world by changing themselves. Now is that over? No. Is the civil rights movement over? No. These movements have not accomplished what they set out to accomplish.

One-hundred facts about Vietnam and we studied the fact sheet and got in to these arguments and it was fantastic, and I remember one moment when we heard two students saying don't talk to those guys, meaning my brother and me. They've just memorized that stupid fact sheet. And we thought, gosh do we sound that good? It didn't seem possible. But that was my introduction to politics.

I wasn't part of John Kennedy's vision of the world, or Lyndon Johnson's. I thought of them as anti-Communist imperial monsters.

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.

In terms of my own behavior and activity, the funny thing about regrets and saying "I'm sorry," is that there's so much I would do differently and want to do differently moving forward.
