A central Texas firearms dealer known as Crockett Keller produced this earnestly xenophobic ad last week.
"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."
While Crockett claims he is excercising his right to teach gun safety to whomever he pleases, The Texas Department of Public Safety has stated, "an instructor that denied service to individuals on the basis of race, ethnicity, or religion would place that instructor's certification at risk."
The department has launched a formal investigation into the matter.
