My cynical take is that it's like a lot of pop. culture, which isn't shocking to its audience (though it might be intense) and is available simply because adults haven't (yet) thought it important enough to screen carefully. Little kids learn about nipples and genitals early enough, after all, and if Freud is correct, they have the instinctive seeds of sexual desire latent in their early fantasies. A good anthology of fairy tales collected directly from oral tradition (
Cinderella in America, compiled by my, alas, recently deceased colleague Bill McCarthy, is a good one) will document this: nudity, childbirth, rolling heads and all.
But the above insight is disturbing to adults, who want to self-censor the origins of sexual feelings and perpetuate an image of childhood as an "age of innocence." It isn't, of course, but when a grown-up finds such a volume in a library accessible to grade school kids, the adult will be shocked and angered and raise all sorts of hell at the school board meeting. And so (alas) if you purchase such a volume, you'll need to hide it from the grown-ups, because it's not psychologically healthy for them.
Another colleague, Josepha Sherman, compiled a very educational anthology of children's rhymes, songs, and chants, titled
Greasy Grimy Gopher Guts, which includes material collected from the "innocent" age group in question. The material makes kids' interest in sexual matters pretty clear, and so it's one of the most frequently banned books in the country. The kids don't need the book -- they already know most of the rhymes. The parents are the ones who are shocked into confronting something they'd just as soon keep in the closet.
Gomenasai for such a long post. It touches a professional sore point.
