What is biracial nationalism? Biracial nationalism or biracial identitarianism is a right wing, political philosophy that seeks to validate the hypothesis that the aggregate total of all mixed race people on the planet today constitute a separate racial category which takes the extant form of a biracial diaspora. This ideology then goes on to propose that the diaspora will evolve over a period of time into a new race of people called the fifth race. The overall goals and aims of biracial nationalism as a school of thought is to imbue mixed race people with a sense of identity and purpose which corresponds to their manifest destiny as the antecedents of this new race.
