This whole subspecies conversation is irrelevant if you look at the definition of race in common language. Race does not have to be a sub-species. In a scientific definition it may but not in common language. When the average person on the street refers to race they are not referring to a subspecies and instead are referring to a category that describes ones ancestry.
