Yeah that was stupid. It's called verification.
It's not even verification. You can't [scientifically] verify something that hasn't ever been tested. You vaguely suggested collecting evidence. How, what, when, where - and most importantly, why does it support the hypothesis?
The fact that the institution repeatedly protected their own priests in their scandalous behaviors
Doesn't mean that all, a majority, or even a significant percentage of individual priests participated in the behaviour or knew about it. The assertion that this was a secret practice of the group suffers from logical inconsistency: the group must participate. You have no facts to bear this out (nor do such statistics exist). If you're going to argue that a practice is a ritual that promotes group membership, you'd better have some hard facts that the group actually engages in said practice.
Without those facts, you can't even begin to test your earlier statements (which are not a hypothesis, because they aren't testable) - and as such, we're back to its status as sociophilosophical bull****.
When you've got something resembling a position based on testable science, post it.
