A note on the whole fact or fiction thing.
I was on the train about a week ago and an interesting little conversation happened. Two people in front of me said that they (I presume they is those who are publicizing the movie) said the movie was fiction, but the book is based on history. I smiled and said nothing. But then the people in front of them said that they heard that and they started talking about how the book is true. I then thought I would get involved and discuss how most of the historical stuff is not really true. At first they wanted to know how I knew that. After I mentioned I was PhD student studying theology they then sort of beleived. But they were asking alot more stuff about the book.
While it is nice to know that many on here discuss it as a work of fiction- there are alot of people, and not uneducated people, who believe that the conspirary theory stuff is true.
It should be noted that Dan Brown really walks the edge of saying whether he believes the historical stuff. By that I mean that he has made conflicting statements. In light of this, I actually do not think it is all that inappropiate to have the "Debunking" books
