Of course, the deeper lesson here is that race itself is a concept invented by racists. Thank you. Although your wording may be a slightly more confrontational than I would have put it (that "race" is purely cultural), you raise a very important point. The word itself has become impossibly overloaded, meaning a poorly defined combination of genetics, national/cultural origin, and current culture. I remember marveling at the admonition on a user's social network page: (paraphrased) "I'm Hispanic, not Asian!" What I find important to note is that the spectrum of meaning of "race" ranges from something an individual has no control over, to something that is pure choice. Although discrimination based on genetics being wrong is something that's relatively uncontroversial, discrimination based on choices/behavior is much less clear cut.
