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.

Yup, this is what they actually mean by "traditional marriage." The traditions are misogyny and obedience.
Gay marriage threatens this by providing a counterexample.
