Currious also, I think a lot of people are forgetting... in 1946, the superman radio show actually had a 16 episode plot called "the clan of the firey cross", in which superman is protecting a Chinese american family, from a clan of evil doers in white hoods. Not only was the group an unsubtle reference to the KKK, but thanks to a mole in the KKK named Stetson Kennedy, it even used real world up to date for the time secret code words from the actual KKK.
