The Catholics controlled Hollywood during its Golden Age. The Hays Code was written by a Jesuit. And Hollywood's Enforcer, Joseph Breen, was a notorious anti-semite.
Famous saying: "Hollywood is a Jewish owned industry selling Catholic theology to a Protestant nation" The KKK used to think Hollywood was a 'Romanist,' not Jewish, cabal.
Hays didn't write the code... He just got it past the lawyers. O, sorry Pharmboy... 'nuther stereotype. (this one is less true.)
