I'm aware of the Mt. Cashel orphanage, but " The boys of St. Vincent" still had to be heavily fictionalized/made composite or they would have just called it "The boys of Mt. Cashel".
I'm in agreement that the pope almost certainly knew about abuse, but I don't know if a meeting in 1967 proves anything. Getting an invitation is not the same as attending. Making accusations or broaching a subject for the first time is not the same as proof or "full awareness." THE PRECEDING STATEMENTS ARE NOT EXCUSING WRONG DOING, but it would be just as if is someone said to me "State employees are crooked." Yeah, there are 30,000 of us and I'm sure one or two are crooked. It would be very difficult for me to accept after working there 25 years that MOST state employees are stealing. (even if most state employees actually did steal.).
