Just my stupid opinion that Indiana's answer will be that there is no license to discriminate. To them this will simple mean that no specific law says you can discriminate. This does not mean that a person can't discriminate, only that the State does not give specific permission to do so. A person can still refuse service or products because there is no law stating that they can't. Then if a person refuses service, he can say it is not discrimination, but simply exercising the laws protection of his religious beliefs.
The State must have a non discrimination law
