Well, yes and no.
Going way back, around 1990/1 he did have a controversial book.
But he himself began saying there are genetic differences in intelligence.
I actually spoke personally with him and was addressing problems of genetically defining race etc...which are real questions. By saying it is genetic, if one were to take him seriously, he would be a bit weak on the science, almost in to pseudo-science.
But he didn’t actually care about real questions. He just wanted to say blacks were inferior.
I felt he had a fair amount of legitimacy at the time, before this interaction, and even after I didn’t think he was straight out NAZI White Supremist separatist type.
I’m surprised where he’s gone and what he’s done.
