Have never noticed that trend INTJs. I think Racism has to do with your impression of the world around you, not type related. Anytype can be racist...to me racism is nothing more then extreme stereotyping. I believe that what can cause INTJs to be racist is there Ni vision, but I dont pin INTJs as racist. From the ones I have interacted with they are not confrontational enough to be racist. Maybe I have just been around healthy ones, who knows.
