I actually think of the two, Malcolm X (his choice of religion, notwithstanding), was the more conservative of the two. He preached self-reliance, and railed against white liberals, proclaiming their policies would do much more damage to black people...and he was right.
Malcolm X, for all his faults, absolutely hated the Democrat party. I think the legend of him is more radical than who he really was. I know it was his own NOI people who killed him for not being radical enough and wanting a martyr.
