Just found this in a wikipedia search just now-
https://en.wikipedia.org/wiki/Malcolm_X
This doesnt really have anything to do with Islam, especially seeing that Muhammad himself was white : p And it definitely seems like his "religious" views were more about race than anything else, and that he hated Christianity not because he thought it was untrue, but because most white Americans accepted Christianity.
I wouldnt take his religious views seriously :
Malcolm X did indeed have some pretty off-the-wall theology. However he did seem to be a man of integrity and only wanted to uplift the black community. I don't agree with all of his philosophies but I do believe he had good intentions.
