American black nationalist groups have been branded anti-Semitic, homophobic, misogynist and even racist by the mainstream press. Louis Theroux goes to Harlem in New York to meet its proponents, and meets the Reverend Al Sharpton, the main point of contact in the black nationalist movement. Theroux also meets Khalid Abdul Muhammad, dubbed by the media ‘the most dangerous man in America’ and visits the Israeli School of Universal Practical Knowledge, who believe that blacks are the true Israelites and that all English monarchs until early modern times were black. Theroux also joins Al Sharpton on a march on Wall Street to protest at the shooting by New York police of Amadou Diallo, who was shot 19 times.
