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.

We all want to believe this American pastoral, but there's more to it. We have to be willing to exile ourselves from the fantasies and the mythology that we create around ourselves, or we're doomed to kind of innocently blunder into every country in the world and murder people.

The Right said, [Barack Obama] is lying, he's a socialist who pals around with terrorists, he's a secret Muslim and blah blah blah. That was their line. The liberals all said, He's winking at me, I can feel him winking in my direction. He wasn't winking. He said exactly who he was and he's lived that out perfectly.

I think that you're smarter than we were, but we had two things: one is, in our naïveté we believed we could change the world. And number two, we believed that another world was possible. And once that belief took hold of some critical mass, a tiny minority nonetheless, but a critical mass of people, then the world did change.

My brother and I met several times during that weekend trying to figure out what we were each going to do, and we met for breakfast the morning of the sit-in and I had decided that I was going to go get arrested, and he decided that he was going to have the harder job and go tell our parents that I'd been arrested.

I was from my little perch in a prep school I saw the civil rights movement and it was defining the moral dimensions of the time and I was drawn to it and I read James Baldwin and read Invisible Man and these were my touch points. But it was when I got to Michigan and saw a bigger world, a real world, that I got involved.

I mean the prime case that you can look at is Martin Luther King, who was only an activist for 13 years. But every year, he became deeper, more concerned, connecting more issues.
