re: "Civil Union" versus "Religious Marriage"

You’re parsing words and it ultimately means nothing in the realm of government. The government recognizes equally (as it should IMO) the contractual union entered into by two consenting adults.. the other stuff is word play.. I could buy the argument that states could ceremonially call them different as long as sanctioned in the same document. Ultimately the church/venue/officiate should retain the authority to call the ceremony what they choose
