Some years ago, my mother-in-law, a theatre director, staged a production of South Pacific at a high school whose students were about 80% Asian, including many of Japanese heritage. Because it made no difference to the plot, she changed or eliminated the derogative term “Jap” from the script. Now, a new edition of Mark Twain’s classic novel, The Adventures of Huckleberry Finn, is about to get the same treatment.
