Why do you want a word that indicates they are biologically capable of having children?

Presumably so they can be told they are not in the correct clinic if they accidentally go to an IVF clinic.

Why do you want a word to describe one type of marriage as opposed to any other? What about a marriage of convenience where they accidentally have children? Do they get another certificate?

Why are you interested in what a gay marriage is about? You can go on websites to find out if you are that interested.

Or is it so bigots can point, stare and judge?

I think we have finally got to the bottom as if were.
