You provide an unspecific example of some organization that supposedly doesn't accept a white member but of course you make no mention of the major American institutions that have failed to integrate (continue to practice discrimination) due to the fact that they are dominated by white people and promote their material interests: the American system of education, political institutions, residential areas (and don't claim that Blacks or Latinos desire to live in racially segregated neighborhoods because peer-reviewed research contradicts that claim), employment. 
From the beginning and continuing today, is the dominant white culture that has instituted the division of society based on race. Race as a social construct was invented by European- Americans to facilitate their dominance of American institutions. Peer-reviewed research is conducted by persons who have obtained degrees from accredited institutions of higher learning. Learn something new, look up what "peer-reviewed" means.
