On January 16, 2006, "Against the Grain" investigated the debate over the legacy of Martin Luther King. In addition to establishing in popular culture the principle that a man should be judged by the content of his character, rather than the color of his skin, King espoused socialism, was proven a documented plagiarist, and cheated on his wife. It is sad that a balanced investigation of a man's ideas and actions is seen as verboten in current American culture, and instead, the "cult of the personality" rules. This is the first of five parts discussing the legacy of King's work for social change, and his less than rosy scholarly and economic ideals.

For more information on King's plagiarism and economics, there are many sites to which one can refer. This is a good introduction to the plagiarism issue, one about which only a few, mostly conservative, people were aware. The link:

It does not make one a racist to study the character of a man. In fact, King's own famous speech set that as the standard.
