Here is a random quote from Frederic Wertham’s infamous Seduction of the Innocent. It’s from chapter one, titled: “Such Trivia as Comic Books”.
“As our work went on we established the basic ingredients of the most numerous and widely read comics books: violence; sadism; and cruelty; the superman philosophy, an offshoot of Nietzsche’s superman who said, ‘When you go to women, don’t forget the whip.’ We also found that what seemed at first a problem in child psychology had much wider implications. Why does our civilization give to the child not its best but its worst in, in paper, in language, in art, in ideas? What is the social meaning of these supermen, superwomen, super-lovers, superboys, supergirls, super-ducks, super-mice, super-magicians, super-safecrackers? How did Nietzsche get into the nursery?”
