The back-story is infamous at this point; Catholic priests have raped children, and the current Pope knew it then and knows it now.
This is from The Independent :
Imagine I discovered there was a paedophile ring running our crèche, and the Editor issued a stern order that it should be investigated internally with "the strictest secrecy". Imagine he merely shuffled the paedophiles to work in another crèche at another newspaper, and I agreed, and made the kids sign a pledge of secrecy. We would both – rightly – go to prison. Yet because the word "religion" is whispered, the rules change. Suddenly, otherwise good people who wouldn't dream of covering up a paedophile ring in their workplace think it would be an insult to them to follow one wherever it leads in their Church. They would find this behaviour unthinkable without the irrational barrier of faith standing between them and reality.
Yes, I understand some people feel sad when they see a figure they were taught as a child to revere – whether Prophet or Pope – being subjected to rational examination, or mockery, or criminal investigation. But everyone has ideas they hold precious. Only you, the religious, demand to be protected from debate or scrutiny that might discomfort you. The fact you believe an invisible supernatural being approves of – or even commands – your behaviour doesn't mean it deserves more respect, or sensitive handling. It means it deserves less. If you base your behaviour on such a preposterous fantasy, you should expect to be checked by criticism and mockery. You need it.
If you can't bear to hear your religious figures criticised – if you think Ratzinger is somehow above the law, or Mohamed should be defended with an axe – a sane society should have only one sentence for you. Tell it to the judge.
