I went back to a small town in Poland where my dad grew up. It was a very traumatic experience for me as a young man to know that my father's family were killed by Nazis, killed by Hitler. And that left, you know, if not intellectually, at least an emotional part of me which said, God, we have got to do everything we can to end this kind of horrific racism or anti-Semitism. And I have spent much of my life trying to fight that.
