Centrists can go suck a fat one. The primary reason we're in this fascistic mess globally is the centrists' aversion to being inconvenienced for the rights of their fellow people and for the future of the planet.

That's what creates dictatorships, that's what starts world wars, in summary, that's what enables fascists.

similarly I understand why Roberts is trying to lower the pressure

Allow me to cite a passage from Kagan on WV v. EPA.

It seems I was wrong. The current Court is textualist only when being so suits it. When that method would frustrate broader goals, special canons like the “major questions doctrine” magically appear as get-out-of-text-free cards.

In short, "weak ass arguments receive rebuttal for being weak ass arguments." The Court is fine to actually start issuing judgement that follows in step with the history of the court. But then you have something like Dobbs and the majority opinion.

The doctrine of stare decisis does not counsel continued acceptance of Roe and Casey. Stare decisis plays an important role and
protects the interests of those who have taken action in reliance on a past decision.

So after indicating that people might plan their lives on court decisions, the majority then begins to explain why "none of that matters" without actually explaining why none of it matters outside of "because unborn babies are important" WITHOUT explaining the "why" of that statement. That's the point of the court to establish the "why" of an argument. It might be plainly obvious to the Justices the why unborn babies are important, it's their job to then hit the letters on the keyboard to spell that out. That's the justice system, you spell it out in insanely ornate detail. That's literally what all lawyers love to do, unload heaps of words onto people. When they do not do that, well then that's how you know they are full of shit.

So no, I dissent here. The Justices must do better and not simply provide weak-ass arguments with nothing but circles for the explanation. The more expansive reading justices are rightly apt to apply heat to bullshit. A weak ass court is only made stronger when it's weak ass arguments and opinions are called out for everyone to read.

That said.

In any case this seems to come back to Congress no longer passing legislation and instead relying on executive powers for all political requirements

That's broad powers. That's how that works. We do not list explicitly every single animal that needs to be on the endangered species list. We do not list in law every single road that will be paved with public works money. We do not itemize in law every single uniform that we will purchase for every member of the military. At some point we just say in law "protect animals that might go extinct", "fix our highways", and "protect our armed forces" and let the Executive dictate how best to achieve those goals. And when the Executive fails on that in a particular way, well they're Congress, they can pass a law that gets more specific.

But even then, when specificity is given, the only thing I hear is "OH NO THIS LAW IS A 1000 PAGES LONG! I CAN NOT READ THIS!" Yeah, who knew complex societies were, IDK, complex?! The Executive powers are JUST THAT, the part of the Government that gets shit done. Congress indicates their broad wishes and the Executive deals out the finer details. How pray tell, is that thinking NOT centrist? How are you left unserved by your supposed current model of governance? Yes, you might be unserved because the political party system is fucked but that is distinctly NOT a function of the balance of power between branches as outlined in our form of government.
