Well, I don't expect The Passion to be very good anyway. The historical inaccuracies alone would be enough to put me off. That said, I wouldn't try to ruin the movie for anyone else by sitting at the back in the theatre and making farting noises every time I heard something I know to be religious and not factual. But that's exactly what the fundamentalists trying to put other people off the movie are trying to do. I'd get kicked out the theatre, they should get moved off the street.
