Why would anyone ban a children's book about penguins?

Because, it's a book about two boy penguins who love each other and together raise a baby penguin. Best of all, it's based on real events in the Central Park Zoo. I read it to my own daughter, and she loved it. It didn't bother her at all that two boy penguins would form a family.  Read more about "And Tango Makes Three" by Justin Richardson and Peter Parnell here.
