BULLSHIT.
Kingdom, Phylum, Class, Order, Genus, Species...and further divisions of sub-species are recognized. Terrapene ornata luteola; Terrapene is the genus, ornata is the species, luteola is the sub-species. Desert box turtle in the common vernacular - one of countless examples. Farming recognizes animal breeds and plant varities. The hominids get divided up too. Of course, taxonomy gets touchy with living human classifications, but competent comparative anthropologist can make an unofficial stab at it.
Race is a "social construct," is what you are claiming. Yeah, sub-species for the rest of the living world, but humans are all one kumbaya happy group. Open your F*****G eyes!
...and, Get over yourself!
