Celibicy is not the cause of homosexual rape of teenage men by priests, but elimination of the celibacy requrement of priests goes a long way towards the cure.
Presently, the Catholic Church has a system in place where a young man, with homosexual desires subtly nagging at him, growing up holy (usually a former alter boy), has an opportunity to deny his tendencies, by becoming "celibate" in a sanctioned, encouraged, manner. Become a priest, and you don't have to worry about those nagging itches. All sexual urges are suppressed equally.
The urges never go away, but the future homo is in a great place to hide them. It must be a great relief, for a troubled, holy man. Feel like doing another guy? Well, nothing to worry about, you are forbidden to do anyone.
Then once in a position of incredible power, surrounded in sanctioned secrecy, among alter boys (teenage men) who worship you, alone with you, with little chance for discovery, in hidden chambers that very few are allowed entrance to, the situation is completely different. It is now a situation where you can easily let those long suppressed urges come forward, with very little risk. A situation perfectly ripe for abuse.
"Lead us not into temptation..."
This is so ripe for abuse.
Now, open the church back up for married men (like it was for 50% of the Catholic Church's existance), and what will happen? They will get a huge influx of men, drawn to God, who are also drawn to women. The overall percentage of homosexual priests will fall dramatically, and the ones that remain unmarried, and who also show no interest in women, will stick out like a sore thumb. They will be watched more carefully.
(Interview question) "Are you attracted to women?"
(Answer) "Uhhhhh....."
Biology is biology. Normal men are strongly atracted to women, and have a very "hard" time not showing it. In an institution that discourages that attraction, and makes men feel guilty for it, you will drive off normal men, and attract troubled young men with homosexual tendencies.
Let's see the study that compares the percentage of homosexual priests in the Catholic Church to the percentage of homosexual priests in the Protestan Church. It has to be out there somewhere. Let's see it.
You need to do some studying. Start with the Council of Elvira, 295-302 AD, Canons XXVII and XXXIII. When you're done let me know and I'll give you some more information to correct your ignorance. By the way, didn't those married men practice continence?

and for starters 2) Child Sexual Molestation by Protestant Clergy
By the way, those Protestants aren't bound by a vow of celibacy.
