I mean hereditary, not cultural, psychological differences between races a traditionally defined.  E.g., there used to be a belief so widespread among Americans whites (and blacks too, I shouldn't wonder, since they never heard a word in contradiction) that it needed no defending, it seemed obvious common sense, that blacks are mentally inferior to whites -- and morally inferior too; that is, too primitive and bestial for moral self-control.  Does anyone here still believe that?
