I agree with your general take that there are at least two schools of antiracism, but I have to quibble with your use of Malcolm X as a model for the second. The man who was a member of the Nation of Islam might be fit what you describe, but the man he became after he left NOI does not.

Two examples of his later thought:

“I believe that there will be a clash between those who want freedom, justice and equality for everyone and those who want to continue the systems of exploitation. I believe that there will be that kind of clash, but I don’t think that it will be based upon the color of the skin.” — Malcolm X, 1965

“I’m for truth, no matter who tells it. I’m for justice, no matter who it is for or against. I’m a human being, first and foremost, and as such I’m for whoever and whatever benefits humanity as a whole.” ― Malcolm X, The Autobiography of Malcolm X
