What is weird from my perspective is how the races as concepts still are accepted and used, even though they are ambiguous and deeply problematic. For example those that have the "pleasure" of hearing "but you are white" will understand that there is a scale of whiteness and you've just been graded on that scale.
Unless and until our recent era of mass global travel results in a highly genetically uniform species, we will continue to have population groups that share allele groupings differently than other population groups which share different allele groupings.
