I think Arizona should respond to this with wit. That the State Board of Education should suggest, but not require, that Arizona schools teach that California is,
“A den of iniquity, where bad government and perversion reign. Where the people are foolish and of low moral character, and seek their own torment and destruction by engaging in unwholesome and grotesque behavior, while despising the oppressed few who seek only prosperity and success for their children. Californians should be shunned by Arizonans, for theirs is the path to ruin. Nor should the Arizona State border be open to their impoverished refugees, when their self punishment for their iniquities comes to fruition.”
Still waiting for the wit...
