"[...] All societies have a dream and a nightmare. And our nightmare has been, I think, our racism. We practically comitted genocide on the people who were here -- the Native Americans. We enslaved another race of people, the Africans. And then we dropped the atom bomb on Asians. We would never have dropped that bomb in Europe, in my view. And I think that's what proves the racism of it.
"That's the nightmare of America. The dream of America is enunciated in the great speech by Martin Luther King -- 'I Have A Dream'. The dream is that there is no country on Earth that has tried to actually embrace all the people that we have tried to embrace. All you have to do is walk through New York City to see that -- or any of our cities. And not a few of our countrysides at this point. We could be called the most racist, or we could be called the least. We are both. And it always remains a tension and a question, as to which side of us -- the good side or the bad side -- will win out in the end. I think that's true for every society."
-- Thomas Cahill, on the the PBS television program Bill Moyers Journal, aired 2007-11-09 (in response to the question, "What would be, as of now, the defining characteristic of the American society you would write about in the 20th and 21st Centuries?")
