Okay so I enjoy good humour mocking any kind of religion and bigoted people and whatnot, but accusing the Pope of being a Nazi is a bit fucked up.
During Hitler’s rule, all children were required to join youth organizations, for example the Hitlerjugend, much like in commmunist states. He is maybe around 12 on this picture, and I think it’s rather safe to assume that he was a member of an organization because it was OBLIGATORY, not because he - cleary a young boy at the time - was a Nazi.
