Then why does Brown make this claim at the book's beginning... “all descriptions of artwork, architecture, documents, and secret rituals in this novel are accurate”.
This is why there is an outcry.
Brown is a despicable liar and a coward.
When called on his "accurate" secret rituals and documents, he and his apologists throw up their arms and say "it's fiction.....it's fiction........"
He can't have it both ways.
This is like all the liberals who swore that the "Passion of the Christ" was going to cause Christians to beat and kill Jewish peoples in retaliation.... When all is said and done, it'll be just a footnote in Pop Culture.
