I wish we would stop using the word "ban". No state literally "bans" people stating vows for one another. Please use the phrase "the state only recognizes" marriage between a man and a woman. There is a big difference. The word ban implies against the law, there is no law that states two men or two women cannot get married. We all assume that it is only a marriage if a secular government grants a license, there are thousands of men/women marriage without licensing.
