I agreed that the writers were probably going for a dig, but in their defense, if they were just portraying what a person ignorant of Catholic rituals might do when confronted with the unknown, I have a true story that could have come off their page.
Then the best case scenario is that you are defending something you acknowledge isn't funny. Why?
the other option is that you brought up your own situation defending the show with the "un-voiced argument" that it IS funny because it could happen. At least that's what it looks like.
