You're probably right about the celibacy thing. According to this article it seems to debunk it. The article also explains the vast majority of the church child abuse is done by homosexual men to young boys. In the general public the vast majority of pedophile cases involve heterosexual men and young girls. It is incorrect for some to say that the priests that are abusing boys aren't homosexuals. Not saying there is zero cases of heterosexual men abusing young boys in the Catholic Church, but it would be extremely rare.
9 Myths about Priestly Pedophilia
That article was written by the Catholic Education Resource Center - you don't suppose they might have planted it as 'damage control'?
Nearly every statement is supported by "there's no evidence", which says only that it hasn't been subject to rigorous scientific study. It does NOT mean their interpretation is correct.
"Celibacy bears no causal relationship to any type of deviant sexual addiction, including pedophilia" means zip when you know the priests weren't victims of "deviant sexual addictions", they were opportunists who found minors the most convenient [but not necessarily attractive] targets for their desires. Some people choose celibacy freely, for awhile, or for life, and it causes them no problems at all - but priests didn't choose it, it was imposed upon them as a condition. If there's any rational reason for that, I've never heard it.
The author insists that very few priests are pedophiles, [an adult who is sexually attracted to children], which may well be true - but if priests are/were abusing children because that's the only outlet available, rather than genuine desire [as in gay sex in prison], what difference does that make to the victim?
The lack of support for various claims & interpretations made says it's nothing more than the Catholic Church's effort to 'spin' the story to absolve the Church of responsibility for their contributions to the abuse.
