We already have it here in the states.
What state is left that continues to define marriage as only between one man and one woman?
I don’t know of any. So the battle is already lost here, literally, until Society by and large retuns to a foundation rooted in God. Or until Jesus returns in Glory. And I don’t see either happening in my lifetime.
At least Oz did it by referendum, instead of by fiat like some states (judges) did, just changing the definition via law suits instead of legislation.
I don’t live under a rock, in a cave, on Mars, so I’m aware of the 2015 judicial fiat, thanks. ;d
I was merely commenting on the fact that I think we’d do about that same as the Oz result if we did have a referendum, 60-40 at best, that’s what current polling is, sadly.
