For Crockett Keller, the customer is always right -- or at least right-leaning.
That's because the Texas firearm safety instructor refuses to teach liberals.
In a radio advertisement that could cost him his ability to teach concealed handgun safety classes, Keller made it clear that an Oct. 26 course at Keller's Riverside Store in Mason wouldn't be open to people who voted for President Obama and Muslims.
"If you are a socialist liberal and/or voted for the current campaigner-in-chief, please do not take this class," Keller says in the advertisement, which is described as "controversial" on his own website. "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," the radio spot concludes.
Keller's restrictions could infringe on the rights of Texans seeking to acquire concealed weapons permits, but the 65-year-old told KVUE that he is just trying to protect his rights as a teacher.
"I call it exercising my right to choose who I instruct in how to use a dangerous weapon," Keller said, according to the news station.
"The fact is if you are a devout Muslim then you cannot be a true American," Keller reportedly added. "Why should I arm these people to kill me, that's suicide."
The Texas Hill Country businessman told The Houston Chronicle he has received many calls from neighbors who are supportive of his stance.
Attempts to reach Keller by phone and e-mail were not returned by Huffington Post deadline.
A spokeswoman at the Texas Department of Public Safety, the agency that certifies Texans to teach classes on concealed handguns, confirmed that the agency has launched an investigation into Keller's business practices.
"The department became aware of the statements in question yesterday and has begun an investigation into the matter," she said in a prepared statement. "The department will take appropriate administrative action based on the findings from the investigation."
