It's strange how books are often judged by different standards than movies. I was just remembering how, in the movie E.T., the kids in the movie call each other "penis breath" and "douchebag" as insults. (By the way, I wrote this BEFORE seeing FacelessWords' post about that, above mine! Too funny.) I found that mortifying when watching the movie with my kids...and would be reluctant to show them that movie again at home for a while, considering how my 6-year-old likes to repeat anything potentially provocative that he hears. But when E.T. came out, most kids in America saw it, & the parents left raving about the cute alien movie and making it a classic, instead of screaming about those words ruining it. Even though those words, in context, are MUCH more provocative and disturbing in my mind than "scrotum." I don't think even my 6-year-old would find "scrotum" particularly provocative.
(Actually, what bothered me more in the sentence from the book was the drinking of a gallon of rum! My kids aren't too familiar with alcohol so I might even have to explain what rum was...but the idea that someone could drink a gallon of it and live sounds like a more worrisome notion for my kids to have in their heads than the word scrotum.)
I guess one difference is that those movies & TV shows aren't normally shown to kids in school--parents decide whether to show them--but still, it seems like a double standard. I think this really is mainly an issue because the word is on the first page of the book, and kind of made a big deal of (with the character wondering about the meaning of the word), so it's unavoidable to teachers or parents, and I also think librarians and teachers would just find it personally embarrassing to read aloud. But that still seems like not enough reason to avoid purchasing a Newbery winner, of all things, which has always been considered a mandatory purchase for children's libraries.
I hope librarians in general don't get a bad rap for this...after all, it is librarians who choose the Newbery winner! I was stunned when I read about this, though, because in my experience librarians are some of the biggest proponents of intellectual freedom that I know of. Though my husband, who has a library degree, said school libraries have a little different situation because of all the pressure from parents and administrators.
