It's alluding to something off-topic, with a hint of "edgy-ness"

Let me be more clear then. Not only will there be many priests sharing private information about their local congregation, there will also be priests who continue to directly abuse people in their communities. Sharing private information is extremely mild in comparison.

How is it off topic? The entire basis of solatic's comment is the assumption that priests would not break the rules. A track record of breaking the rules is reason to not make that assumption.
