Technically speaking, he is clearly a racist, if we define a racist as someone who believes that there are biological hierarchies of cognitive ability among selected groups of people and that society should be organized according to these hierarchies.

That's textbook racism, in fact, and he's written many posts elaborating on it.

The soundness of his judgments on Swedish immigration policy are not even relevant to the matter, so please stow the misplaced and self-righteous knee-jerk schizodoxia, Hooah. Despite what certain types will tell you, being friendly with a racist does not "make you evil". With that relief granted, you should hopefully be able to remove those blinkers.
