DAN BROWN said that his books are "fiction". What if I will make a novel about his wife being RAPED?
Well, that is just a fiction.:)
A novel. lol
I hope you get my point.
Dan Brown uses "real" and "sensitive" things which he uses for his profit like the Church, Mary, the Opus Dei and even Jesus Christ.
Fabricating the truth and making his "own" story.
He will the call it "a novel".
Simply because "attacking the Church and Christ is a strong business".
