QUOTE : One hundred years ago my great-grandfather thought women shouldn't vote. He was absolutely certain about that, and I'm absolute certain he was wrong. Two hundred years ago my great-great-great=great grandfather believed that white men should own black men. He was absolutely certain about that, and I am certain that he was wrong. I'm humble because I don't know what I'm wrong about today. I'll speak with confidence and I'll speak with passion, but I won't speak with certainty.
