We do not know that she is not rightfully scandalized. Sorry that I did not cover that properly, but I did say in an earlier post in this thread that she should not propagate it as a rumor and not report it without firm knowledge. See the earlier post.
What about innocent until proven guilty? This is not fair treatment of the OP at all.
Rumors and gossip are wrongful things. However, it is also wrong if someone who is legitimately concerned to be attacked for it. You are exactly right when you say we know nothing about the OP’s situation. Therefore, we should not be treating her in a critical manner.
The proper response is simply to address the question:
Yes, IF it is something you have firm knowledge of, then you should tell the Priest. IF it is not, then do not. And no matter what, do not talk to anyone else about it.
What is wrong with a reasonable and balanced response?
Instead, people decide to attack the OP, call her self-righteous, and imply unkind things about her intentions. Well, that is no better than what she is being accused of, is it?
