"Racism is still a major issue because it is a habit. It is a devastating disease. But it took us 370 years to get to this place and 200 years to establish racism. It won't be obliterated by the passing of a law or the charismatic presence of a Malcolm X or Martin Luther King It will be a tedious process and a long one. We will have to have people with strong and big hearts working for a few generations to obliterate the ugliness of it. There's something little spoken of. In the early 1800's, Thomas Jefferson wrote a letter to a friend saying that we should send the slaves home to Africa. Why? Because, he said, it will take us five generations for them to forgive us."
