The full-frontal male nudity gets no reaction.
There's plenty to say about censorship of young people's reading material, and it's a discussion worth having. But often, I think the debate can be more about adult politics than about the children and teens both sides are trying or ostensibly trying to defend. The human body is old news to kids who've had help getting dressed, and I suspect that many of the other issues that come up in censorship debates are fairly dull to kids (though in some cases, that may be less true as they get older). Arguments often arise over one potentially objectionable scene, one image, even one word. It takes more ink than that to make a story, and it takes a good story to hold a reader's interest. "Once upon a time there was a scandal" may not cut it.
Happy Banned Books Week. Go read what you feel like reading.
