Response to Look At This Lesbian PSA From 1938:
Keep in mind that Hays was a former Postmaster General who was hired as a mouthpiece for the Film Board. The movie code was the direct result of the Catholic Church threatening a mass boycott of movies if the industry didn’t clean up its (alleged) dirty act. Today’s movie ratings are the result of that intrusion. My facts might be a tad off, but you can verify via the book or movie, The Celluloid Closet.
