For the multiculturist
diversity crowd, culture, ideas, customs, arts and skills are a matter of racial membership where one has no more control over his culture than his race. That's a racist idea, but it's politically correct racism. It says that one's convictions, character and values are not determined by personal judgment and choices but genetically determined. In other words, as yesteryear's racists held: race determines identity.
