The South Park episode was not an argument of any intellectual worth. I don't think it was meaningless, but the meaning was to insult rather than to dispute anything. Just like, if instead of posting arguments to you I would begin insluting your mother, then this conversation will lose all value and become a nuisance to you.
I’m pretty sure the episode's meaning was to challenge the idea that alcoholism is a disease that can’t be controled through self discipline, and they made a pretty good argument for it considering the media. The silliness of pilgrimages to fluid dripping statues was just approached as self evident, and then exaggerated in South Park style as a tool for developing the meaning of the episode.
No need to wonder how it would effect me if they slammed something “sacred” like my Mother. As an Objectivist for 15 years now, I was spun around in 1998 when they said “Atlas Shrugged” was “garbage” that “totally sucked a~s”. Guess which one of these guys is me. I wonder if I could get anyone who says that banned for blasphemy.
