P.J. O'Rourke on Amy Chua. Ms. Chua is the author of the bestseller Battle Hymn of the Tiger Mother: "You might think that Amy Chua is a fascist pig. She wrote a previous book, World on Fire: How Exporting Free Market Democracy Breeds Ethnic Hatred and Global Instability, so she is. She also possesses the most unpleasant personality I’ve ever seen projected into print, and I’ve read Earth in the Balance."
