Respectfully, that really just sort of kicks the can down the road. (That's probably on me; I could have worded it better.) What is it that made these Justices suddenly so open to promoting this idea in their opinions? Have the Justices changed their views on it (or at least found it suddenly more 'acceptable' to start discussing it openly), or was it baked into the nomination of people like Alito, Thomas and Scalia (and now the new batch of Trump's nominated Justices)?

I guess what I'm really asking is how far back this goes. It's easy to view the modern GOP as just throwing any old shit at the wall to see what sticks, as long as it keeps them in power -- and I definitely think there's a strong case to be made for that -- but it also kind of feels like it's been seeded for a long time, and we're now seeing the direct result of that because the Trump administration fluked/scammed their way into three SCOTUS seats in four years. (I guess the parallel would be with the overturning of of Roe v. Wade, where it seemed to fall apart very quickly but there's also evidence that the GOP have been setting up their little chess pieces for a long time through things like the Federalist Society.)

When we're looking for a cause for this -- and with the understanding that situations are nuanced and events are very rarely caused by only one thing -- is it a 'modern' (post-2016) issue, or do we need to be looking a lot further back into history to get the context for this?
