I just had a realization.
It was (and is) always so confusing when The Bad Straights claimed “gay people getting married will ruin the institution for everyone.”
But I think they always meant that if two men or two women can get married, then marriage must not be defined by a man obtaining a woman as servant/property & securing exclusive rights to her labor, identity, & body.
And without that, they can’t even imagine what purpose marriage could ever serve.
