Haas, a Corpus Christi native, is the author of 200 Years a Fraud, in which she disputes what she considers historical inaccuracies in Twelve Years a Slave, an 1853 memoir by Solomon Northup. In her book, Haas argues that U.S. history is overly harsh on the South and doesn't acknowledge that slavery was "a socially acceptable and economically worthwhile practice worldwide at the time our thirteen colonies arose."

The woman who campaigned against these history books has her own book which is full-on historical revisionism akin to the Daughters of the Confederacy.
