I agree ... but the fact that they have been ordained is a function of ideology, not of celibacy. The American Catholic heirarchy has been loaded with leftists, and they've tended to cuddle gays instead of monitoring or dismissing them.
The Boy Scouts realized the problem and instituted highly-effective screening procedures, along with security procedures for every adult, in about the same time period that the Church leaders here were going limp. It's a phenomenon of recent history, in my opinion, and the celibate priesthood is not a recent invention.
It's interesting that the public schools have not yet made the slightest effort to protect the students from sexual predation, either by teachers or by other students. One suspects this is because they are even more sheltered from (ahem) feedback than the Church heirarchy.
A few months ago I took a class from a Evangelical-turned-Anglican Priest-convert. He was married with two or three kids. He didn't even try to become and ordained priest. He's trying to get a dispensation to become a Deacon and he's teaching high school for the archdiocese. He was very inspiring.
A serious study of the schools would show that sexual deviants are shunted from district to district as part of the dance of the lemons.
