> HB 1069 required that school librarians remove materials from their collections that contain “sexual content,” regardless of the value of the book
Florida cannot ban private libraries from stocking books with sexual content. But librarians are government employees buying books and maintaining libraries with government money. The state can direct its employees what kinds of books to make available for the same reason any private entity can do so.
This might be different if libraries were neutral venues for authors to come present about their books. In that case you might have a case about viewpoint discrimination. But the first amendment can’t force the government to buy particular books and make them available to the public.
