There are some areas of black life in which excellence can be found without the slightest hint of racial preferences. Young blacks dominate basketball, football and some track-and-field events despite the fact that there has been a history of gross racial discrimination in those activities. Blacks are also prominent in several areas of the entertainment industry. Those observations mean that racial discrimination alone is not an insurmountable barrier to success. By the way, I can't think of any two fields with more ruthless competition.
You say, "OK, Williams, everyone knows about the success of blacks in sports and entertainment, but what about the intellectual arena?" A few inner-city junior high and high schools have produced black champion chess players, schools such as Philadelphia's Roberts Vaux High School and New York's Edward R. Murrow High School. Last year, two black teens -- from Intermediate School 318 Eugenio Maria de Hostos in Brooklyn, New York -- won the national high-school chess championship. All of this is in addition to quite a few black international masters and grandmasters in chess. Moreover, there's a long list of former and current black inventors and scientists. So there's no question that black people have the capacity to compete intellectually.
Civil rights organizations and their progressive allies, who all but suggest that blacks cannot achieve unless they are given special privileges, grossly insult and demean black people. But worse than that, when civil rights organizations and their progressive allies pursue special privileges for blacks in college admissions and when they attack academic performance standards as racially discriminatory, they are aiding and abetting an education establishment that delivers fraudulent education. They let educators off the hook, thereby enabling them to continue to produce educational fraud.
