Are you serious? Catholic priest TODAY may choose not to wear their collars but, back then they all wore them, proudly, I might add.
Go look up what happened in Holland, I believe it was, after the Nazis found out about the Catholic churches and convents hiding Jews. There WAS a round up of priests and nuns.
Also read about St. Maximillian Kolbe and Sister Teresa Benedicta better known as Edith Stein.
Those top Nazis may have called themselves Catholic but obviously they weren't as noted by their actions.
Your point being??????? Stein was gassed because she was born a Jew. Period. You can't "dejudaize" the Holocaust which is what Gibson is trying to do.
