"The problem with weak versions of racial naturalism is that they do not contrast with anti-realism about biological race. When race naturalists weaken their position they end up agreeing with their opponents about human biology, and defending a trivialised definition of race. Weak racial naturalism is wrong on semantic grounds." (Hochman, 2014) So called "race realism" today is race denialism. It's proponents have weakened their position entirely that "race realism" is actually anti-realism. http://www.academia.edu/7667337/Unn...ND_PHILOSOPHY_OF_SCIENCE_PART_C_2014_46_79-87 I mean Mikemikev is only arguing "race" is a concept with predictive power. This is not a natural or extra-mental (real) argument for race at all.
