Another example of fear-based religious fundamentalism that sees a fiction as a threatening fact. Dan Brown's novel is a fiction, a Hollywoodesque jaunt based on conjecture and myth. It contains murder, sex, intrigue and love. Hmm, pretty much like the Bible. This supposedly 'scientific' debunking of what is perceived to be one of the great threats to Christianity proves nothing except that the film makers could gather numerous opinionated people to spout conjecture. It is not a scientific argument to assert that Da Vinci had no quarrels with the Catholic Church if you've just contended that very little is known about the life of Da Vinci. What a load of rubbish! Don't waste your time.
