Awesome post slingblade.
Yes, when someone is seriously trying to say evolution is a hoax to undermine religion, which they do say often, I roll my eyes. I'm so used to hearing it though, I wouldn't be surprised to see a "Da Vinci" book on Darwin.
I don't know if I'd get "up in arms about it", since I am used to hearing it.
In fact, I'd like to see someone even try to get a popular work of fiction out on that! How would they do it. I'm darn curious

Darwin actually existed, and you can look at the facts around his existence to prove his real motives...knowledge. Jesus didn't exist, so you can say he liked purply flying pigs if you wanted to. Just cause the bible didn't say so, doesn't mean he didn't. Couldn't have captured ALL his likes and dislikes in one book!
I guess, based on that, I have to applaud the author of DaVinci Code for getting so much attention over this whole thing.
Mind you, if something like evolution (which is observable and based on fact) gets them going, then the book must have something in it that is hard for them to refute, and that is why they are "up in arms".
Hm. Gotta go see the movie and see what it is that they figure must seem true, even though it isn't observable nor fact based. *scratches head*
Again, that is why I find this all so confusing. They are both works of fiction, so one really can't undermine the other. They will both simply exist, and people will still choose to believe what they want to, since neither is based on anything observable or factual. It's not like evolution, where we know it's silly for someone to say a living cat can just suddenly evolve into a dog. We can refute it with facts. There are no facts to refute in the DaVinci situation.
So the cunundrum of fiction. You cannot refute fiction with more fiction. It's like using the flatness of the earth to try to prove the moon is also flat. Neither is true, so you can't prove either. Instead, you have to look at the earth and moon, take a pic, and decide based on fact instead of trying to prove either is flat.
It's all just so silly!
So, take the bible as end all, and there you have it. It isn't in the bible. So it didn't happen. Problem solved. DaVinci Code is fun, but it wasn't in the bible, so it's not true. Easy enough.
I hear there are supposed jesus decendants. Well, test their dna...
