We will let you have your civil-union to your buddy so long as you love him and consummate the relationship forsaking all others.
Anyway I want a different word for marriage between those of a religious persuasion. After all when I marry my dear sweet atheist girl I don’t want our marriage to be tarnished by all that associated ”wrong thinking’ that comes with the religious ideas those people have. Therefore I want those of faith who want to get ”married’ to accept the new term “religious union”. It will still offer all the legal recognition of real marriage but not the name (to which it has no right of exclusivity anyway)
