Those people who would flock to a bleeding statue or some other apparition of Mary in mold on a window, or in a piece of toast, are the only target for mocking in the episode.
If you don't like the show, that's fine... Matt and Trey will still eat tonight. I am merely correcting errors of fact that you, and others were making, in describing a show you haven't even watched.
But that is NOT what the argument is about. You clearly miss the point, that being that this statue is representative of the very real Virgin Mary, and for the sake of a few laughs at those who might "flock to a bleeding statue or a piece of toast", by showing blood pouring out of various orifices (whether statue or not), indicates a presence of sacrilege. And that's NOT NICE. And those who find the South Park episode/segment to be over the line have a right to feel that way, whether you miss their point or not. And you DO, and you ARE. Additionally, based on the various posts of others concerning this, including yours, is it really necessary for me to actually SEE the segment (we're not talking Gone With the Wind here, are we?) to offer an intelligent argument against ONE thing in it? I didn't realize we were talking about the entire series, were we?
I looked at my festivus pole, and I saw the image of finely machined aluminium alloys. It was a miracle! I went out and bought some green and red peppers to celebrate!
Praise Festivus!
