I think even that's an exaggeration, but it saddens me that it's just an exaggeration, and not false.
However, it won't get very far. It will get farther than it should, but I think if it gets egregious, the current SCOTUS will, in fact, stop them. For example, the previous poster mentioned poll taxes. Those are, explicitly, unconstitutional. I think if they tried a poll tax, SCOTUS, including this one, would stop them.
It's unfortunate that the vast majority of citizens see Supreme Court rulings solely in terms of their effects, and not on the legal issues behind them, but that's life. It's even more unfortunate that some of the justices themselves seem to do the same. (I'm looking at you, Clarence.) However, neither Kavanaugh, nor Gorsuch, nor even Barrett have proven to be rubber stamps for the GOP. I don't see that changing, and I don't see any of them going for blatantly unconstitutional rulings.
And, that's right. If you inferred that I don't see overturning Roe v. Wade as blatantly unconstitutional, you have inferred correctly. I think there's a legitimate argument that Roe v. Wade went beyond constituional bounds, and for the first time in 50 years, a majority of the court agreed with that argument. I don't see that as a constitutional crisis.
I do see that as a crisis for individual rights, which is why I think people need to pay attention when they vote.
