There seemed to be a thread running through a lot of the posts in support of boycotting The DaVinci Code. There's a theme of "poor me." Everybody's picking on the-fill in the denomination of your choice. It's all a conspiracy by the-fill in the target of your choice. Most of them were pretty foul mouthed too. Also very creatively spelled in a lot of cases. There were also some very well thought out entries running along the lines of "if I don't agree with it nobody is forcing me to watch it or read it."
The Creator/ress existed long before humans realized she/he existed and will exist long after we're gone. My beliefs are mine, I'd prefer not to believe alone but my belief or lack of belief is not conditional on what you believe. My belief or lack of belief is not conditional on what some novelist writes or some script writer creates based on that book.
I seem to be having some trouble finding the right words to express this and I don't want to come across as a sanctimonious ass. If a piece of fiction can shake a faith perhaps the problem is not the book or the movie.
