James Cone is a Black Liberation theologian, if theologian is really the word here. He's one of Jeremiah Wright's inspirations, and most people don't know what he's about, so you should check out this article by Kathy Shaidle:

The leading theorist of Black Liberation Theology is James Cone. Overtly racist, Cone's writings posit a black Jesus who leads African-Americans as the "chosen people." In Cone's cosmology, whites are "the devil," and "all white men are responsible for white oppression." Cone makes this point without ambiguity: "This country was founded for whites and everything that has happened in it has emerged from the white perspective," Cone has written. "What we need is the destruction of whiteness, which is the source of human misery in the world."

If whiteness stands for all that is evil, blackness symbolizes all that is good. "Black theology," says Cone, "refuses to accept a God who is not identified totally with the goals of the black community. If God is not for us and against white people, then he is a murderer, and we had better kill him. The task of black theology is to kill Gods who do not belong to the black community ... Black theology will accept only the love of God which participates in the destruction of the white enemy. What we need is the divine love as expressed in Black Power, which is the power of black people to destroy their oppressors here and now by any means at their disposal. Unless God is participating in this holy activity, we must reject his love."Small wonder that some critics have condemned black liberation theology as "racist idolatry" and "Afro-Nazism."
