'I am very real'

In October of 1973, Bruce Severy - a 26-year-old English teacher at Drake High School, North Dakota - decided to use Kurt Vonnegut's novel, Slaughterhouse-Five, as a teaching aid in his classroom. The next month, on November 7th, the head of the school board, Charles McCarthy, demanded that all 32 copies be burned in the school's furnace as a result of its "obscene language." Other books soon met with the same fate.
On the 16th of November, Kurt Vonnegut sent McCarthy the following letter. He didn't receive a reply.
