Lots of priests, throughout the ages, have failed to live up to their vows of celibacy. Thousands upon thousands. When they are all consenting adults, what the church wants to do about it is none of my concern, just as it’s none of my concern if a priest does anything else that I consider morally neutral.
What you seem to be doing is saying that if the church has standard X the rest of us should be outraged if the church doesn’t enforce that standard to our satisfaction, if there’s any way that not enforcing that standard could ever, likely or not, bleed over into breaking law Y. But because you’re using hindsight, you are making a connection between things that are not necessarily related.
If he had been found fondling bins of women’s underpants in Target, something that is weird and offputting but not (as far as I know) a crime, and someone complained to the church and the church didn’t announce to the entire congregation that their priest was an underpants fondler, then later that priest molested boys, would you be making the argument that his underpants fondling was an obvious sign that he should have “had someone with him”? How about if he drank three beers instead of two at the pub? How about if he liked to sing karaoke to gangsta rap? How about if he wore a t-shirt to bed that said “Kiss me, I’m Irish”? How about if he loves foie gras and veal? All of these things might raise some eyebrows, and I’m sure some people would use them as evidence he was unfit to be a priest, but would you be trying so hard to connect the dots if it turned out he molested children?
This is where the disconnect lies. You are explicitly tying his past actions (hitting on young men) with a fear of his being a pedophile, but hitting on young men, whether you’re a priest or not, does not appear to the rest of us to be a good clue that you are a pedophile-in-waiting. The two lack any connection for those of us who are arguing against you. They are not connected simply because they are both about sex. They do not become magically connected simply because he is a priest. They do not become magically connected simply because the RCC is a bunch of hopeless bigoted idiots who conspired to hide evidence of child molestation in other cases.
Not revealing someone has sexual urges toward young men is not the same thing as not revealing someone has molested young children. They are not equivalent acts in any way, shape, or form.
