“In a sane world, the term “ban” would be reserved for books whose sale and circulation are illegal in some given place, and “censorship” would refer to the removal, by some legal or commercial authority, of certain portions of a text or film or recording. (I say “commercial” authority because sometimes companies that own the rights to works of art decide, without legal pressure, to delete some lyrics in a song or change certain words in a book.) But thanks to people who want to smear their RCOs, it is now common to use precisely the same words to describe (a) what the nation of Iran did to Salman Rushdie’s The Satanic Verses and (b) a polite letter from a parent to a school librarian asking that books that offer anatomically detailed descriptions of sexual practices not be readily available to third graders. Of course, many concerned parents are not polite, but polite letters on this topic still count, for the ALA, as a “challenge,” and the organization defines a challenge as an attempt at censorship or banning.” Alan Jacobs
