Following the social upheaval of World War II, many people in the United States felt a fervent desire to "restore the prewar social order and hold off the forces of change", according to historian Barry Adam. Spurred by the national emphasis on anti-communism, Senator Joseph McCarthy conducted hearings searching for communists in the U.S. government, the U.S. Army, and other government-funded agencies and institutions, leading to a national paranoia. Anarchists, communists, and other people deemed un-American and subversive were considered security risks. Gay men and lesbians were included in this list by the U.S. State Department on the theory that they were susceptible to blackmail. In 1950, a Senate investigation chaired by Clyde R. Hoey noted in a report, "It is generally believed that those who engage in overt acts of perversion lack the emotional stability of normal persons", and said all of the government's intelligence agencies "are in complete agreement that sex perverts in Government constitute security risks". Between 1947 and 1950, 1,700 federal job applications were denied, 4,380 people were discharged from the military, and 420 were fired from their government jobs for being suspected homosexuals.
