There are attributes that matter with race, though. Whether we term it "race" or some other term does not matter, we all do fall in to some "buckets" when it comes to gene or allele expressions. I agree that there is some geographical context as well. Black people in the US are more susceptible to certain conditions such as diabetes, based on both, geographical (racial biases, perceived or real) and gene expression. In my opinion, I think you are over-simplifying this. Ignoring gene expression over geographical is very unreasonable. There are evolutionary and adaptive features, not to mention selection, that do incorporate geography in the development of those expressed genes. Still, the genes expressed vary and can, at least, phenotypically be sub-categorized.
