I'm anti-establishment. So all the labels, the reason that I keep joking and rejecting this idea that I'm liberal, well partly that's because I think of myself as a radical, and by that I mean, not even in the terms of Left-Right that you might imagine - but someone who wants to go to the root of problems.

I thought in 1965 that my job was to convince most Americans to be against the war. So I spent summers knocking on doors, handing out literature, trying to talk to people who didn't agree with me, trying to get them to see the war was wrong. And by 1968 a majority of Americans did oppose the war.

I was arrested in 1965 for opposing the war in Vietnam. There were 39 of us arrested that day. But thousands opposed us. And the majority of the people in the country supported the war then.

Who's the big government guy? These labels are nonsense. And the Tea Party, if you want to call them working class, you know, a working-class insurgency from below, they are a mass of contradictions; they don't have a single consistent viewpoint; but part of their impulse is to be wary of government.

I more or less shared the view that life should be lived.

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.

When I was arrested opposing the war in Vietnam in 1965, as I said about 20 or 30% of people were opposed to the war. By 1968, more than half of Americans were opposed to the war. If you pull in Europeans, Canadians, people from around the Third World, the war was vastly unpopular. But even half of Americans by 1968 opposed the war.
