I also remember the year before. 1962. There were cases taking out God's name from public school. Also remember we almost blew up the human race in the fall of 1962. The Cuban missile crisis. I was born that year. I remember my mother telling me how they all were praying when president Kennedy told the nation finally. She was in special prayer groups. Which by the way is the best thing he did. It brought every God fearing prayers into real heart felt action to save our existence. If you see the movie Thirteen days. You will see a scene were the Churches were bursting at the seems when the advisor of the president himself goes to Church. All of sudden you had a revival for God. But did we learn from this? No . The following year we took more of God out of the schools then Kennedy was shot.
I only saw this in Ny right after 9-11. The church's and Jewish temple doors were jammed open to show everyone they were welcomed. Then more people going in to church. Days after.
Also remember the upheaval that was the sixties that brought these radical ideas to the world.
No movie rating system was needed before the mid-sixties.
