And Tango Makes Three is one of my favorite banned books. It is based on a true story of 2 male penguins at the Central Park Zoo in NYC, who raise an egg together. It provides a great example for kids about families which come in all variations. Based on an actual event, it allows the reader to explore his/her own observations about how adults take care of their young. An especially important message of tolerance can only be a positive in a world much to ready to judge and hate on sight.
