The Good Book is being treated like a bad book in Utah after a parent frustrated by efforts to ban materials from schools convinced a suburban district that some Bible verses were too vulgar or violent for younger children. And the Book of Mormon could be next. The Davis School District north of Salt Lake City banned the Bible from its elementary and middle schools in response to a parental complaint. After news of the Bible ban, the district said it received a complaint about the Book of Mormon. This all comes as parent activists throughout the United States sow alarm about how sex is talked about in schools.
