though I think it’s unlikely to directly have the intended effect and will probably just prevent people from confessing instead.

That’s the thing, if you violate the confidentiality of confessionals then people simply won’t confess, and then you lose the avenue for a priest to try and convince someone to address their behaviour. Maybe that’s not very effective, but it’s more effective than not having it.

In line with your assessment of the article’s agenda, I have to question how much of an issue this even is. Like, the Catholic church has a long history with child abuse, but wasn’t that primarily about Priests abusing children in their parish, and the church protecting its priests? This is an accusation that Catholics themselves are a bunch of child molesters, which is not something I’ve seen any evidence in support of.
