Just thinking out loud...
Maybe a different type of contract could be added for one man-one woman marriages only. Couldn’t the states simply give it another name if it can’t be called just marriage now?
Then one man/one woman couples would have the option to choose “marriage” and/or this other category.
And also, allow churches to marry couples as a sacrament without the civil marriage.
That was the idea behind Civil Unions, but homosexuals refuse to be placated. They demand your glorification of their deviant sexual behavior or you will be punished.
Regardless of how you feel about homosexual marriage, the fact remains that what we are witnessing is pure tyranny. Under no circumstances can this edict be seen as a legitimate law in a representative republic.
At least they took a vote in Ireland.
