If you mean repression caused by celibacy - and not some sort of cultural repression - then no. Pedophilia is a deep seated psychosexual deviancy, not something that gets turned on like a light switch.

And two other issues with this logic:

1. No one forced these guys into the clergy nor is priestly celibacy some sort of surprise.

2. If someone is willing to break their celibacy (due to it being repressive) to prey in kids, wouldn’t they be just as or more likely to break it to sleep with an adult, if the celibacy was such an issue for them?
