AIDS and Drugs: The disproportionate incidence of AIDS and drug use among blacks prompts prominent figures to endorse a conspiracy theory that the U.S. government is behind these epidemics. The comedian Bill Cosby asserts that AIDS was "started by human beings to get after certain people they don't like." The movie director Spike Lee announced (in an advertisement for the Benetton clothing shops, of all places) that "AIDS is a government-engineered disease." On late-night television, rap singer Kool Moe Dee portrayed AIDS as a genocidal plot against blacks, with no dissent from host Arsenio Hall. A mass-circulation magazine for blacks ran as its cover story, "AIDS: Is It Genocide?" Steven Cokely, a well-known former Chicago municipal official, gave the plot an antisemitic twist, telling of Jewish doctors who injected black babies with AIDS as part of a plot to take over the world. Drugs and crime inspire similar fears. In the acclaimed 1991 movie about black life, Boyz 'N' the Hood, a character proffers a full-blown conspiracy theory about crack and guns being available to blacks because "they want us to kill each other off. What they couldn't do to us in slavery, they are making us do to ourselves."
