The MO law attempts to enforce a religious viewpoint. It's offensive to anyone who does not believe that life begins at conception and is unconstitutional. The Satanic Temple's claim is legitimate. Their belief that the body is inviolable and subject to one's own will alone is just as sincere and important to their lives than the beliefs of a Christain - which is one reason why the state cannot enforce a singular religious viewpoint over another.
