If you haven’t already, I’d suggest reading this Tim Wise essay. It isn’t entirely compatible with modern-rationalist epistemology, notably in that Wise seems to reject (or at least resist) the idea that science has much to say about ethics. But Wise does make a strong case for distinguishing the possibility of biological racial differences from a defense of racial inequality.
