"I think that's a very uncharitable and inaccurate view of the Pope. He is dealing with a 50 year crisis going back to John XXIII that spans the globe."

The clergy pedophilia crisis started in earnest in 1922 and therefore it is almost 100 years old, not 50 years old. Read the book "Potiphar's Wife: The Vatican's Secret and Child Sexual Abuse", by Kieran Tapsell. And it is likely that clergy pedophilia and cover ups by Bishops started when the Church decided to enforce celibacy since the 12th century: this has been going on for more than 800 years.

"There is no way he going to be able to just clean that all up in 4 years of his Papacy."

How long does it take for a Pope to fire the hundreds of Bishops that covered up clergy pedophilia because Church Law orders them to do so? Five minutes or five years?
It is obvious that the Vatican strategy is to wait until you and me and everyone alive today are dead and then pretend that the clergy pedophilia cover ups by Bishops never happened.
