One person had a Missouri high school ban Kurt Vonnegut's classic novel Slaughterhouse-Five. Of course he had no kids in the school but the board quickly caved and pulled the novel from the shelves. After being called out for national embarrassment, the school reinstated the book, making Slaughterhouse-Five available to kids who have parental approval.
Having parental approval? Reading is a matter of discovery and challenging your thinking, so vital in the high school years. Slaughterhouse-Five was a revelation to me during my own adolescence. I've since reread the book time and again, and used it in my English 102 classes.
Of course Slaughterhouse-Five will be attacked again and soon. It's a perennial favorite of book banners...and burners. Yes, it was burned in a South Dakota school in an infamous case Vonnegut detailed in his book Palm Sunday.
Here's the most recent story and here's Vonnegut's 1973 response to having his book burned in 20th century America.
