First off... are these people cracked? I think that no one who has actually watched this film would come away from it thinking that the Python folks were making fun of Jesus. His followers, sure... but not the man himself.
Second, WTF are they thinking in this day and age, trying to ban anything? When you can order a DVD to be delivered to your door ... what does this ban mean anyway? Just a symbolic poke in the eye to Monty Python?
Finally, I think it's hugely ironic that this town banned this film, and yet elected for its mayor the woman who played Brian's girl friend. Complete with a brief nude scene. Just.... DAMN!
