Given that all humans share a remarkably high % of genome, and race is a social construct, I'm struggling with the 'this is not genetic' part. Either its a truism, or its backed by strong evidence of no genetic linkage. Because this 'its not your race' thing, applies to almost anything. For instance the supposed Asian intolerance to unmodified milk proteins which has been changing as diet shifts. Is that also now not actually genetically determined?

Human and pig genomics are also very similar. It's not the 98% that make or break these things. Lactose intolerance is inherited and as a result of LCT gene not expressing due to downregulation by another gene MCM6.
