Complete bullshit. True racists are basically self-taught anthropologists. A crude brute incapable of telling the CLEAR difference between a Thai and a Chinese would not be welcomed in the racism community. The ascended, magi racists can identify the subtlest, almost imperceptible differences. They can distinguish between a northern and southern Somalian - and concoct culturally specific, historically accurate slurs for them both - without hesitating.
