Exactly it is crazy like gay marriage. Who is the husband and who is the wife? Who is the one who can sign legal documents and who can't? Things are now all fuzzy and indistinct. We need to go back to the old days of clear and simple.
You either have very little ability to understand concepts, or you are deliberately obtuse. Marriage is not a fuzzy word. You either define it as the union between a man and a woman, or between two consenting adults, or whatever. But whatever definition you use, it's pretty simple and easy to understand.
Not so simple with the definition of gender, or so we're told. Your analogy fails.
