The most challenged book of the year, though, was "And Tango Makes Three," a picture book that told the true story of a pair of male penguins in New York that receive an egg to nurture. The objections were varied: it was anti-ethnic, sexist, gay, anti-family, it had an inappropriate religious viewpoint and wasn't suitable for children -- all of this despite excellent reviews from both School Library Journal and Booklist.
Apparently no one objected that reading the book might make the kids want to grow up and be penguins.
