Arizona shares a border with Mexico and Mexican-Americans make up a bit under a third of its citizens. Prior to the Mexican-American War, Arizona was even a part of Mexico. Despite the facts, Arizona declared ethnic studies illegal in 2010 and quickly banned Tucson's Mexican American studies program.
The state's attorney general at the time said that high school classes focusing on Mexican American history were "propagandizing and brainwashing." Tucson school board members feared that teachers were indoctrinating students through burritos -- seriously. The Ninth Circuit, thankfully, brought a little sanity back into the conversation, ruling this Tuesday that the law was at least partially unconstitutional.
