Well, but then Harry Potter is a problem for all grades, not just first, and should be on a "parent permission" shelf. Mind you, I feel this is an insanely slippery slope. The number of kids' books with "occult" elements is huge.
The question is whether they provide practical or theoretical tips for creating dark cults, or similar items. They really shouldn't be anywhere.
Just like "how to create nuclear weapons in a suitcase" should not be on the shelf at all.
At some point you realize that some books really have no business existing.
