"The numbers are actually much higher among public school teachers in terms of the raw number of cases and percentages."
They certainly are. And, if you bring in stepfathers and boyfriends, it's even worse.
There is no question that a small percentage of RCC priests molested youngsters, and that the church, in some cases, did not deal with them properly.
But other denominations have had the same problem, and have acted in similar ways, and sexual abuse of children is a problem in all classes that work in close contact with youngsters.
"Rampant" is not a word I'd use to describe any of those classes.
