The purpose of the Communists in Hollywood...

"The purpose of the Communists in Hollywood is not the production of political movies openly advocating Communism. Their purpose is to corrupt our moral premises by corrupting non-political movies — by introducing small, casual bits of propaganda into innocent stories — thus making people absorb the basic premises of Collectivism by indirection and implication.

Few people would take Communism straight. But a constant stream of hints, lines, touches, and suggestions battering the public from the screen will act like the drops of water that split a rock if continued long enough."
