I won't dispute you on point 2. I don't agree, but I don't think we would convince each other of much on that topic.
It's a logical outflow of the position that an unborn human child is an unborn human child, but, yeah, that will probably be something we just disagree on
Right now the majority of moderates view SCOTUS as a political body more than a legal one. This opens up the door, over time to, changing the number of justices, restructuring SCOTUS in other ways, and anything else, because now its mundane. It lowers that threshold to a future arms race which not only has harmed our society, but is very likely to do further damage.
Respectfully, the Left spent
decades using the court to do an end run around our democratic means of governance to achieve
political victory on issues that weren't as popular as they wished they were - Roe is a classic example, as is Obergefell. Pushing a political question into the Court, meaning that any opposition has no choice but to go
through the Court, and then complaining that
your opponent has politicized the court is....
... Do you understand the level of chutzpah that comes off as? That sounds to others like how you would hear Trump fans accusing Democrats of lowering the level of our public discourse by leaning into personal attacks.
From your link:
Democrats were used to thinking that they got to win at SCOTUS. Then they discovered they could lose. Republicans already knew - from decades of experience - that they could lose. The movement you are identifying is being driven by folks on the left.
As for the "Majorities opposed to overturning Roe", Meh. Issue polling on that is a problem, mostly because people generally don't know what Roe did or was; but identified it loosely with You Know, Like, There Can Be Like, Some Abortion, I Guess, You Know, and thought an overturn meant a ban.
When you ask Americans to sit down and chart out their actual preferences, you end up with a result that is frustrating to the activists and politically oriented folks of both sides - Americans tend to come down with a sort of European Approach, that allows abortion generally in the first trimester, and starts to sharply restrict it as the child ages. That, however, requires overturning ROE.
If the SCOTUS, after this trick, continues to be out of step with American culture, then popular support for changing its structure to reign it back in will be less and less shocking to voters. SCOTUS may not be vulnerable to popular perception in the short term but it certainly is over time if actions are taken little by little. The door is now open for that.
The Door has been opening for that since Roe, which - along with other attempts to use the Court to help "Progress" society - helped turn Presidential contests (and, to a lesser extent, Senatorial contests) into an all-or-nothing contest over who would get to appoint the Judges that determined the major questions for our society.
People who went to church on a weekly basis voted against Trump in the 2015/2016 primaries.... and came out en masse to vote for him in November 2016 - because of Roe. I was the first person on this forum to identify the fascistic tendencies of the Trump movement, and to declare myself NeverTrump, and Roe is the only thing could have pulled me back - and, had I known for a fact that my vote would put him in, and that he would appoint the justices that would end Roe, I would have. Because, at the end of the day, we had put so many major decisions in the hand of the court - the mass murder of children! - that nothing else mattered, compared to it.
You may say "God bless McConnell" but he hurt our country badly. I suspect by point #2, you may see that as worth it.
Congress has long since ceded far too much of its power to the Executive. No, I am not upset to see it take some of it back, or to challenge a President on a SCOTUS nomination. You are correct that I would be willing to take the damage you describe in order to overturn Roe, but, I think where we are seeing this differently is that I am pointing out that
this damage was already done.
