"The Perks of Being a Wallflower" has appeared six times on the American Library Association's list of 10 most-frequently-challenged books for its content. A Wisconsin school board refused to ban the book, angering local parents. The Glen Ellyn District 41 school board in suburban Chicago unanimously voted to reinstate the novel after it was removed from eighth-grade classrooms at Hadley Junior High School because of a parent's objection to its sexual content. Groups like PABBIS (Parents Against Bad Books in School) work to restrict literature considered "controversial" from being accessed by younger children. The group believes these "bad books" should be moved to the adult section. In 2009, "Perks" was repeatedly challenged for descriptions of masturbation, sexually explicit conduct, drug use, and talk of suicide, and there have been multiple pushes across the United States to move this literary work from the children and young adults section to the adult section. Parents have raised issues with the novel for its "pornographic" content and "vulgarity," but others have argued that the book deals with real and common teen issues concerned with growing up, so it presents a truthful viewpoint. Issues are also raised surrounding the book's themes of homosexuality, as well as a "glorification" of the use of drugs and alcohol. In an interview, Chbosky said that he knew of two school boards which have banned the book (in Massachusetts and on Long Island). Since he "didn't write it to be a controversial book," he was "surprised" by the bans.
