Chris Higgins writes: “The Des Moines (Iowa) Register obtained a list of 374 books that the Urbandale Community School District believes could violate Senate File 496, which, among other changes, requires teachers and administrators to review their libraries and classrooms for books that depict sex acts and prohibits them from buying them in the first place. The law also prohibits schools from providing instruction about gender identity or sexual orientation before seventh grade, which Urbandale officials believe includes books, according to instructions provided on the list.”
