Anything other than that is/was simply not a "marriage".
It really is that simple.
Marriages that never happened (inter-racial marriages) in a culture are meaningless.
What's meaningful is the marriages that did happen, in that, no matter what the mix or lack thereof racially in the marriage, if said relationship is "between a man and a woman as husband and wife" then it was still a marriage, and if it wasn't, then it wasn't.
Again, it really is that simple.
Activists and other ideologues are compelled with creating the quick-fix oxymoronic "gay marriage" reference of marriage to allow SS couples.
But, of course, that doesn't make it any more accurately correct to call same-sex relationships a "marriage" than it does to allow cats to be included in a dog show and still call it a "dog show".
The ludicrousness of referencing a SS couple's relationship as a "marriage" is simply that.
"homosexual marriage" or "Homarriage" would be a more accurate term.
