A children's book about two male penguins that hatch a chick together has been pulled from school library shelves in Loudoun County, Virginia.
Parents complained that the book has a gay agenda and have called for its removal. But supporters say the book's removal is censorship.
The decision by Superintendent Edgar Hatrick is being criticized by many parents and gay rights advocates. They say the school system shouldn't have allowed one complaint to limit children's literary choices.
The 2005 book is called "And Tango Makes Three." It draws on the real-life story of Roy and Silo, two chinstrap penguins at the Central Park Zoo in New York.
A spokesman for the Loudoun schools said Hatrick thought the book's content might not be developmentally appropriate for some students.
