Margaret Mead was a famous anthropologist and a friend of hers named Jo Danna wrote a book called the Sicilian project in which she tried to expose some of the misconceptions of the culture, fueled by stereotypes of the Corleonesi.
Of course many more people saw "the godfather" than read her book, because its easier to watch drmamtic movies then read historical books.
The founders of Uriels, having taken refuge with Sicilians to escape the problems in their own families, participated in a Sicilian project of their own, and saw firsthand how devoted the Padrinos were, not in a hypcritcal way but with an ancient unaffected sort of piety that is misunderstood by present day society.
They saw no contradiction in attending daily mass and then shouting tutte cazzate at anything they didnt understand
This is not to say the padrinos were angels. No, they are human. And so are we.
Learning the truth about Corleone, the city of a thousand churches, is not required but is recommended to understand the road that led to Valanga
