I believe this shit, or the cover up for it was still going on even fairly recently, so acting like this was ancient history is nonsense. Obviously they won't put out an arrest warrant for the Pope, but they should be demanding all records pertaining to this stuff and be investigating those involved, and be talking about revoking whatever their special religious status (tax exemptions, etc) is in Canada if they don't. Until these organizations face real repercussions for this behavior it won't change.
That wasn't his statement though. He's not looking to change the institution. He wants to end it, and hold Francis alone accountable for every crime ever committed (Francis is current Pope, by the way...not Benedict).
I could care less about the Catholic church, I hate it as a religious organization just as much as the next ex-Catholic. But I can also think rationally, which I don't think the OP is capable of.
He believes that the Pope should be the sole target of all of his (and everyone's) ire over the actions and non-actions of the Catholic church, despite his documented changes in the Vatican and church since he took power.
I agree that the church should be held accountable, and changes need to continue in order to avoid these types of cover-ups and scandals in the future. I just don't think putting Francis in cuffs is even a rational idea, much less an action that would accomplish anything.
