Sounds like ONE listener complained about it.
It is probably the same listener that wound ban any book that they think of not good for others like The Great Gatsby, by F. Scott Fitzgerald. The Catcher in the Rye, by JD Salinger. The Grapes of Wrath, by John Steinbeck. To Kill a Mockingbird, by Harper Lee. The Color Purple, by Alice Walker. Ulysses, by James Joyce. Beloved, by Toni Morrison. The Lord of the Flies, by William Golding.
While there are some books that truly promote hate or truly or racist, these song nor these books are not.
Sometimes the PC movement is way out of line, over one freaking listener, who can easily change the channel.
