After Indiana Republicans passed a license to discriminate law, a restaurant called Memories Pizza in the Hoosier town of Walkerton stepped up last week to make sure potential customers knew its religious rules: “No Shirt, No Shoes, No Certification of Heterosexuality, No Service.”

It seems pretty clear cut. Former presidential candidate Carl Perrin spent some time in Indiana. He was stationed there in the army and he went to graduate school at Indiana University. He has no plans to return to the Hoosier State, but he wonders, would he get served now if he ordered a slice at Memory Pizza? The shoes and shirt would be no problem, but where do you get a certificate of heterosexuality? He has been married three times, each time to a woman. Would that be enough, or would he have to get official certificate some place? Would the Memory Pizza people take his word for it that he is 100 percent heterosexual, or would he have to offer some proof, like making a pass at a female employee? If people are going to make rules about things like certificates of heterosexuality, they should make it clear how one get such a certificate.

Please do not take this as a criticism of the right of people to defend their religious beliefs. If I remember correctly, one of the Ten Commandments is “Thou shalt not sell pizza to homosexuals.”
