It is spiteful and immature, but I’ve done this: placed pseudoscience-y books in more appropriate sections of the library/bookstore.
I remember when Behe’s magnum opus came out, I would casually sneak it over to the Fantasy/Sci-Fi section. Unfortunately, it would usually fit between Greg Bear and Greg Benford, so I always felt a twinge of remorse for subjecting Darwin’s Radio to Darwin’s Black Box.
