damn you lefties are STUPID
the human brain has developed over MILLIONS of years, and 40 years of lefty liberal whitewash cannot overcome that history.
humans are small tribal critters living in a massively complex society.
your brain EXPECTS your females to find a mate from the tribe just over the hill, not from those crazy motherfuckers 5 hills over, not from among the swamp people, and certainly not from the degenerate forest people or those dangerous tundra dwellers.
human society and the human brain strive to maintain social continuity, as a survival mechanism. your shock at discovering one of your own breeding with a person from a foreign society is natural, and understandable, especially for somebody from a dominant society.
only brain damaged idiots would blithely accept those from a successful tribe adopting the ways of a failed and tribe and thats what your brain was telling you. your new "in-law" may be as Cliff Huxtable as a motherfucker, but his skin still screams "Failure" so the primitive parts of your brain are screaming "hit him on the head with a rock and give your sister to Atook, or even Lar."
this reaction is NORMAL, and when Cliff Huxtable finds himself around people who expect, by virtue of his blackness, that he is part of THEIR tribe, he will get a huge ration of shit about his "snowflake", especially from that tribe's females.
what you are experiencing as a secondary emotion over your primary reaction is White Guilt, a symptom of liberalism and acceptance of a destructive social meme.
your initial reaction may not have been racist, but White Guilt sure as fuck is. White Guilt is the most dangerous and destructive racism ever developed. might wanna look into scrubbing White Guilt from your psyche.
