The distinction is salient. In the same way that ballot harvesting must be distinguished from ballot stuffing, so too should be Court packing be distinguished from partisan withholding of consent to fill seats with partisans. But I can tell you are unmoved because you feel your side has taken it lying down for too long, so you feel you need to say to justify naked partisan power grabs as a "balancing of the scales", NWRatCon. Just do not presume to claim your politicians are any better in principle. You may say your goals are more laudable, but the methods by which you would wish to achieve them are no less foul.
I was going to like your post until I read all of it. My only disagreement at the outset was that you said "the distinction is salient". I maintain it is not. And, frankly, your analogy is not. Ballot harvesting is a process of moving
valid votes to the polling location. The correct analogy would be voter suppression vs. ballot stuffing, which are both dishonest ways of manipulating the votes themselves. Now, I will concede that the
Republican version of "harvesting" is to change the valid votes in an invalid way...
And, as you know, I have complained about Democratic party mischief as well - e.g., gerrymandering. I'm against the practice, period, regardless of who uses it. That is not what is at issue here. As you also know, I have been a critic of the Supreme Court and certain forms of "judicial philosophistry" for some time. There is a parallel here - the ideologues' version of "originalism" distorts the actual judicial principle the same way that the Republicans have manipulated rules of procedure to abuse the process of decorum.
I also detest the lazy argument that "both sides do it". When one actor is 90% guilty and another 10% guilty, a rational person can easily distinguish the difference. One of my greatest disappointments as a prosecutor was actually a conviction - a Soldier who was an accomplice in a gang of thieves was the only one who was convicted, as the ringleader was discharged on an action approved by my superiors (with no conviction), and the more guilty lieutenant made a deal to testify for a discharge in lieu of Court Martial. That is the situation here. The misdemeanors of the Democrats are no comparison to the aggravated felonies of the Republican party. That's just reality. It's not partisanship.
I approve of neither stacking or packing, but I can absolutely recognize the motivation. What's more important to me, though, is the quality of the judiciary, and there is no question that the Republican party has put partisan advantage and ideological viewpoint ahead of judicial temperament and qualifications. The literature, and case reports, is full of that reality.
