Hmmmm...geee...so, are you claiming you bunch don't burn books?
Orrr....are you arguing that atheists shouldn't use books as paper?
I guess I don't understand what your question really is.
I don't advocate burning books, ever. That being said, a book which is widely available, and is printed on delicate paper, often makes really good rolling papers, so....you know, practical need may overcome philosophical reluctance, and then there's the fact that the bible's fictional and stupid, and often the source of hurt and hate, so....I'd twist one, if I had no alternative.
