"Clan of the Fiery Cross"
In 1946, Stetson Kennedy, a human rights activist, infiltrated the Ku Klux Klan and other white supremacist terrorist groups.[5] Concerned that the organization had links to the government and police forces, Kennedy contacted the Superman producers and proposed a story where Superman battles the Klan. Looking for new villains, the producers agreed. Kennedy provided information, including details of Klan rituals, to the writers. The result was a series of episodes, "Clan of the Fiery Cross", in which Superman took on the Klan. The trivialization of the Klan's rituals and natures had a negative impact on Klan recruiting and membership numbers
