If you want to take advantage of the Texas law that allows adults to carry a concealed handgun, Crockett Keller will be happy to help you learn how to handle your sidearm—as long as you didn’t vote for President Obama or are a Muslim.

Keller, a licensed gun dealer authorized to train and certify handgun owners for handgun carrying permits in Mason, Texas, is paying for radio ads to voice his twin passions—gun advocacy and distrust of Muslims, socialists and Obama supporters, according to Reuters.

Keller said in the ad for his class on how to effectively use a concealed pistol, “If you are a Socialist liberal and/or voted for the current campaigner in chief, please do not take this class.” Keller goes on to explain that you will be barred from taking his class because…“you have already proven that you cannot make a knowledgeable and prudent decision as required under the law.”

Keller’s approach to teaching may trigger a challenge to his gun instructor credentials. After Keller’s ad began in Mason, a town about 120 miles away from the state capital in Austin, the Texas Department of Public Safety issued the following statement: “Certified instructors are required to comply with all applicable state and federal statutes, and conduct by an instructor that denied service to individuals on the basis of race, ethnicity, or religion would place that instructor’s certification at risk.”

Reuters has reported that the department has initiated an investigation into the matter.

The class, typically a one-day course, teaches gun carrying methods and gun use, in addition to how to clean and maintain a handgun. Texas allows adults to carry concealed weapons if they have successfully completed a class similar to that being advertised by Keller.

Keller wrapped up his radio by saying: “With no shame, I’m Crockett Keller. Thank you, and may God bless America.”
