From Walter E. Williams:
Suppose a speaker said that sickle cell anemia is genetically determined and occurs almost exclusively among blacks. Would Professor Hopkins stomp out of the room, charging racism? What if it were said that a person's chances of being a carrier of the gene for Tay-Sachs disease, a disease without a cure, is significantly higher if he is an Eastern European (Ashkenazi) Jew? Would Professor Hopkins barf and charge the speaker with anti-Semitism?
Jon Entine, in his book "Taboo: Why Black Athletes Dominate Sports And Why We're Afraid to Talk About It" (1999), says, "All of the 32 finalists in the last four Olympic men's 100-meter races are of West African descent." The probability of such an outcome by chance is all but zero. The genetic physiological and biomechanical characteristics that cause blacks to excel in some sports -- basketball, football and track -- spell disaster for those who have aspirations to be Olympic-class swimmers. Entine says, "No African American has ever qualified for the U.S. Olympic swim or dive team. Indeed, despite a number of special programs and considerable funding that have attracted thousands of aspiring black Olympians, there were only seven blacks who could even qualify to compete against the 455 swimmers at the 1996 Olympic trials."
Do you suppose Professor Hopkins would charge Entine with racism? The only behavioral genetic explanation that campus anti-intellectuals unquestioningly accept is that homosexuality has genetic origins.
