The Official Stephen King Web Site includes a column about censorship that was first published as a Guest Column in the March 20, 1992 issue of The Bangor Daily News.
While this is an older column, it is well worth reading the full text. What I found especially valuable is its advice to all parties involved in a censorship issue. This is what Stephen King would say if he felt he needed to take time out from his work to defend it.
First, to the kids: There are people in your home town who have taken certain books off the shelves of your school library. Do not argue with them; do not protest; do not organize or attend rallies to have the books put back on their shelves. Don't waste your time or your energy. Instead, hustle down to your public library, where these frightened people's reach must fall short in a democracy, or to your local bookstore, and get a copy of what has been banned. Read it carefully and discover what it is your elders don't want you to know. In many cases you'll finish the banned book in question wondering what all the fuss was about. In others, however, you will find vital information about the human condition. It doesn't hurt to remember that John Steinbeck, J.D. Salinger, and even Mark Twain have been banned in this country's public schools over the last 20 years.
Second, to the parents in these towns: There are people out there who are deciding what your kids can read, and they don't care what you think because they are positive their ideas of what's proper and what's not are better, clearer than your own. Do you believe they are? Think carefully before you decide to accord the book-banners this right of cancellation, and remember that they don't believe in democracy but rather in a kind of intellectual autocracy. If they are left to their own devices, a great deal of good literature may soon disappear from the shelves of school libraries simply because good books -- books that make us think and feel -- always generate controversy.
If you are not careful and diligent about defending the right of your children to read, there won't be much left, especially at the junior-high level where kids really begin to develop a lively life of the mind, but books about heroic boys who come off the bench to hit home runs in the bottom of the ninth and shy girls with good personalities who finally get that big prom date with the boy of their dreams. Is this what you want for your kids, keeping in mind that controversy and surprise -- sometimes even shock -- are often the whetstone on which young minds are sharpened?
Third, to the other interested citizens of these towns: Please remember that book-banning is censorship, and that censorship in a free society is always a serious matter -- even when it happens in a junior high, it is serious. A proposal to ban a book should always be given the gravest consideration. Book-banners, after all, insist that the entire community should see things their way, and only their way. When a book is banned, a whole set of thoughts is locked behind the assertion that there is only one valid set of values, one valid set of beliefs, one valid perception of the world. It's a scary idea, especially in a society which has been built on the ideas of free choice and free thought.
