Two Princes - No Waiting

Overreaction reigns in North Carolina, where parents of an elementary school girl are holding a book hostage. The book in question, King & King, tells the story of two fairy tale princes who fall in love. The girl brought it home from the school library. Her parents, who claim "it is not in our beliefs" (I'm not sure what "it" is, exactly), now have the book. It doesn't appear that the book was required reading for the girl's class or that she was in any way forced to read it. Nevertheless, the parents are holding it hostage and are considering legal action. Where are those right-wing anti-lawsuit hawks when you need them?
