FWIW, that wasn’t an accurate description of the exchange. Saintly_Loser was accused of being reckless by leaving his kids alone with a Catholic priest. Nobody said he was actively cooperating in abusing them.
You may find it relevant, then, that Saintly_Loser brought up the fact that he trusts his kids with a priest specifically in the context of a discussion about child abuse by the Catholic clergy, to rebut the argument that priests aren’t trustworthy.
The whole thing was in this thread., if you want to slog through it for the full context.
