I blieve this book is aimed at children aged 4 to 8. Those kids are not going to see this as censorship, or be cynical about the politics of it -- unless adults with an agenda work very hard to "explain" the situation to the kids.
Imagine you gave this book to some kids, and then on further reflection took it away, on the grounds that it contained something 'inappropriate.' When I was that age, in that situation, the book would have stayed in my mind and perhaps I would have made an effort to find it again. Similarly, the tv shows kids really want to watch are the ones they aren't supposed to watch. On the other hand, if you leave a book like this in plain sight, it will never generate more mystique than a boring, mostly ignored picture book about a family of penguins deserves.
