Mason County, Texas, is notable mostly for being the only place in the United States to have a piece of public art inspired by the book Old Yeller. It’s also home to Keller’s Riverside Store, a general store owned by one Crockett Keller, who recently cut a radio ad announcing that his store would refuse to offer training lessons to Muslims and Obama supporters.

Here’s the offending ad, which has prompted an investigation from the Texas Department of Public Safety:

“If you are a socialist liberal and/or voted for the current campaigner-in-chief, please do not take this class. You have already proven that you cannot make a knowledgeable and prudent decision as required under the law. Also, if you are a non-Christian Arab or Muslim, I will not teach you the class. Once again, with no shame, I am Crockett Keller. Thank you and God bless America.”

I can accept the premise that Crockett Keller might have some sort of prejudice against Muslims, because Islamophobia is pretty widespread in the United States. But non-Muslim, non-Christian Arabs? Who exactly is he referring to—the Druze?
