Childless marriage has never been a problem before, why should it now?
However, equating a duplicated HALF of marriage perpetually desolate and barren is simply idiotic denial of the most basic essence of marriage; a cross cultural constraint on evolutionary mating behavior.

That still fails to address why infertile couples should be allowed to marry. And, it fails to explain why same-sex marriage is problematic. Marriage wasn't instituted as a "cross cultural constraint on evolutionary mating behavior." Even if it were, it wouldn't explain the presence of polygamy in many societies at various times throughout history.
You are trying to equate a couple who has the possibility for children with a couple who has NO possibility for procreation while ignoring the basic essence of marriage; a cross cultural constraint on evolutionary mating behavior.
A fact that exposes ss couples as a defective, desolate failure of mating behavior. At the fundamental level, unqualified for marriage.
Moreover, polygamy is either the attempt to address mating behavior's passion or product.
