This is going to be a tough one, and that particular can of worms could very well reenergize an incredibly demoralized Democrat base. I've always been a proponent of the play with regard to the question of gay marriage is simply to redefine any union authorized by the state as a mere "union" or literally any other word. It doesn't really matter what the fuck it's called, it just needs to be something that delineates between the state recognition of legal benefits and the actual sacrament. That way, social conservatives still get their claim over the sacrament of marriage without gays sullying it by making it into a mockery, without all the messiness of "they are taking away our rights" or whatever.
I just don't really see a path where that's a viable focus for the near future, I think that bandaid has been ripped off, people just don't really give a shit anymore, and why should they? Just because the state gives somebody a piece of paper doesn't mean that somehow legitimizes it in the eyes of God. A realistic social conservative win would be putting troonery in the crosshairs, particularly when it is targeting children. That's going to be a win that doesn't require generational effort, but it will also save us all from a massive societal headache in future generations. It will spare us the troon groomers of the future, as well as the tragic detransitioners who will never again be made whole.
