German children’s book against religion

Apparently, the German Family Ministry is trying to get a children’s book critical of Judaism, Christianity, and Islam “to be included on a list of literature considered dangerous for young people.” The book includes religious figures depicted in unflattering, broadly stereotypical ways.

Now, it looks like the book is indeed offensive, in the sense that if I were religious, I’d certainly be offended by it. But I don’t know how much of this would be religious hypersensitivity. Children’s literature has to be graphic, perhaps highly stereotypical. And I wonder if there’s any other way to try and act against the unwarranted sweetness-and-light stereotypes of religion that tends to be much more dominant in children’s media.
