Most states have specific laws on the books that outlaw discrimination based on race, religion, sex, etc. Those laws are protected under the strong compelling governmental interest exception. What Indiana lacks versus say Connecticut, a state with a RFPA, is the law protecting sexual orientation and gender Identity. Connecticut has those laws, so the RFPA only serves to stop things like local governments making laws that ban religious expression, such as building code inspectors ticketing Jews celebrating Sukkot by making temporary shelters in their yards. In that instance, the temporary shelters are not subject to Certificate of Occupancy rules.
