But, Homo sapiens is not a race. It is a species. And technically, we are all Homo sapiens sapiens (for whatever good being a subspecies is).
All in all, race is simply a phenotypic aspect of the human species. Race is not expressed in the genetic code, perse. Race is really just a cultural definition that is in no way used other than by people who wish to define others similar to themselves or different from themselves, as x1xBladex1x's dictionary.com copy-pasta denotes. In an ideal world, it doesn't matter what you look like. It's how big your e-penis is.
