University profs are well-aware of the diversity scams, but they just play along and don't make waves. It's a game. From Elizabeth Warren and the Frauds of Diversity:
Warren’s ploy is not that much more egregious than the thousands of Caucasians with Hispanic surnames who pass as minorities in American universities. White Chileans, Argentines, and Mexicans come to American colleges and are transformed into “Chicanos,” a category that has little reality outside a college campus. Hiring Basques or Spaniards counts as increasing “diversity,” even though they have nothing culturally in common with the mestizo or Indian children of farm-workers. So too with African or Caribbean blacks, who are hired not because they bring the unique perspective of their homelands to their intellectual work or teaching, but because they count as “black,” and thus are assumed to have some mystical connection with American black students and their cultural identity, which owes much more to American culture and history than to African.
Of course, socio-economic differences among American minorities are also ignored in the rush to promote diversity. A Mexican-American dentist’s or schoolteacher’s daughter who never cut a grape or washed a dish supposedly has some special insight into poor or working-class Mexicans. A light-skinned black son of college-educated parents who grew up in the suburbs gets to campus and suddenly has a rapport with the “brothers” and their experiences. An upper class Chinese is thought to be better able to relate to anyone designated by the meaningless category “Asian-American,” which obscures the fundamental differences and histories of Chinese, Japanese, Koreans, Thais, Laos, Vietnamese, Cambodians, and Hmong. The social capital that comes from education and wealth and that is used to define “white-skin privilege” suddenly has no value when it comes to the equally privileged ethnic “other.”
