You may have seen that an administrative law judge in Arizona, Lewis Kowal, just upheld the decree by the State Superintendent of Public Instruction that Tucson’s Mexican American Studies program violates state law. Judge Kowal found that the Tucson program was teaching Latino history and culture “in a biased, political, and emotionally charged manner.” According to CNN, one lesson that the judge objected to taught that the historic treatment of Mexican Americans was “marked by the use of force, fraud and exploitation.”

Try this “history detective” experiment. Ask the next person you encounter to tell you what they know about the U.S. war with Mexico. More than likely, this will be a short conversation, because that war (1846-48) merits barely a footnote in U.S. history textbooks.
