There’s a lot in your comment that’s not necessarily right or wrong, it’s just harder for me to untangle, so instead I’ll address this very salient point:
you could also easily say constitutional organizists want to strip back any equality or progress our society has made via the courts.
The argument of originalists is very specifically that progress shouldn’t be made via the courts in the first place. It’s not the judiciary’s job to push us forward as a society, it’s their job to interpret the Constitution as it’s written. As soon as you open the door for a judge to push us “forward”, you invite them to define for themselves what “forward” means. I don’t think I can understate the damage that would do to this country if the shoe were on the other ideological foot and Christian nationalists were free to decide that “forward” means putting women in the kitchen as subservient partners in a heteronormative nuclear family. And you’re right that the really sinister problem with this particular SCOTUS is that they seem to pick and choose when they want to abide by their stated principles, but on its face originalism is more in line with what the Framers had in mind. It’s just that they also had a lot of other understandings about the American experiment which turned out to be laughably naïve.
The only way to get out of the moralizing doom loop you’re describing is to revert back to judges/justices being neutral arbiters of written law. It’s not foolproof, mind you, because it’s subject to the whims of overt partisans like Thomas and Alito, but it does have a certain philosophical consistency that’s hard to deny.
