Priests have access to and multiple layers of control over a great many individuals. Even if abused, the god-fearing parents will ensure they continue to be in contact with the priest - in fact, it’s not hard to see that your kid being made a special steward of some goblet or something is a ‘promotion’ for the family in the community and therefore enhances the importances of that relationship.
I wouldn’t be surprised to know that there were parents who deny their children’s’ stories, either wilfully or unconsciously.
I was once invited by a nice postman to attend a meeting in a secluded spot where I’d get some sweeties. I wanted the candy, but wasn’t silly enough to go alone. I was young enough (about 7) to formulate an argument as to why my friends should also get treats. Thankfully, he wasn’t there, and the astonished fellow I approached to enquire as to the whereabouts of my treats made no bones about informing us of our ill-advised course of action, and he made very, very sure to get every detail he could about the odd fellow who extended the invitation.
So in terms of paedophilia as a condition rather than as a label on a set of actions, I’d agree the prevalence is much, much higher.
As a parent, I see the care I and others take with who my kids can be trusted with, which is a further indicator of suspected high prevalence - it can actually be extremely hard to definitively say whether one custodian or another is not a danger to the kids’ wellbeing. You just cannot take chances with this one.
Which is all really upsetting, but perhaps that’s just reality biting.
