I sometimes think that religious books are of more interest to me because I'm an atheist. It's nice to know about for when you get a lot of flack over not being religious, and even nicer to know more about religious tradition/books than the book criticizing you!

Definitely understand on book tastes. I'm not that much of a fiction person myself. I have things I really like and I'll never stop reading fiction, but I'm a pretty straight reader.
