So, only white people can assimilate then? The now many generations of people of Hispanic origin that are part of the American story would seem to indicate you are wrong. As is the case with the now multiple generations of Koreans and particularly Japanese, who remain part of the US story even after being put into concentration camps because of precisely the same sort of prejudice, that they were somehow inherently un-American due to their "cultural incompatibility", i.e. non-whiteness, unlike the millions of German-Americans in the US at the time. The Muslims will (continue to) integrate as well. It takes a couple of generations.
