There's an excellent post on Malcolm X and the radical left in mid-1960s America at Collective Resistance. It begins:
'Predictably enough the it’s the shagging around and CV tampering that excite most comment about Manning Marable’s new biography of Malcolm X. But his life story does throw up many more interesting questions about his political evolution and his relationship with the far left.
For example, could socialists have a relationship with members of a cult who believe that white people are an inferior version of Black people, the result of a genetic experiment conducted 6000 years ago? Or have a constructive dialogue with someone who made public statements six months ago that inter-racial marriage is “evil”? Or invite prominent, recently expelled, members of such a cult to speak at their meetings and give interviews in their papers?'
