I had sent him a SATIRE email called The Smell Dogs Really Love: The Da Vinci Cr@p
It is a take off on changing the word "code" with a smelly word that also begins with C. In this case the word is analogous to horse manure, dog manure, buffalo chips, cow pies, bird do-do, etc.
I have tried to do it in a tasteful way (pardon the bun) and place a stigma on those reading the book or seeing the movie (you spent $15 to see a bunch of horse manure/dog cr@p/bird do-do...)
After this is all about a BROWN book and a BROWN movie.
Why not call it a piece of cr$p.
I can certainly understand fundamentalists, especially those unsure of the roots of their faith condemning the book on its substance, but the writing is far above average, and I am an avid reader of mysteries and thrillers. I'm not sure what your standard is, nor whether you have actually read the book, but the money I spent was well worth it. Brown has taken some controversial historical references, some facts, and built a brilliant fast moving thriller.
Perhaps you and your Catholic friend also found State of Fear also a piece of crap. Funny that none of the Catholics/Christians on this site condemned that book. After all, it does exactly the same thing, only with the environmental movement.
