The Bible defined marriage for me, apparently the govt defined it for you. Good luck with that.
So you have your definition, the Book of Mormon has it’s definition, as does the Quran, and whatever book the gay goat church wants to use, to you they are all equal in defining marriage.
Which means that in America, there would no longer be any sense in using the word “marriage”, because it would have no meaning or definition, would give no information.
