White Power Gone Viral

If one is a relativist, or an advocate of identity politics in general, it isn't clear to me on what grounds one can oppose white nationalism. If one cannot utter the term Islamic Terrorism, much less denounce it, or finds Black or Latino Power attractive, the only argument against White Nationalism is that they belong to a different, less desirable tribe. But that of course, won't do the job of convincing anyone to not subscribe to the ideology. My suggestion would be to return to the principles of individualism vs. collectivism and focus on individual rights versus group rights, ideas which this country was founded upon and the initial civil rights movement espoused.
