Artificial performative grievances aside,
this also somewhat undermines your whole thing.
It actually illustrates my point. Before nuking the filibuster, Obama initially nominated Patricia Millett, who worked for Republican admin.
She was specifically chosen as a concession to Republicans (she was assistant US solicitor general under Bush) because Obama preferred bipartisanship and acceptance than his own agenda. The Democrats tried again with Nina Pillard & then again with Robert Wilkins, and only when all 3 were filibustered did it become evident the Republicans would obstruct no matter what and it was impossible to reach a compromise.
On the other hand, Trump went far right and nominated Gorsuch without any pretense of bipartisanship and unity, and then Republicans just nuked the filibuster to push their partisan agenda.
The smart thing for democrats now would be to stop entertaining the filibuster and political norms the other side doesn't respect and few Americans know about, and do everything in their power to push measures like minimum wage and radical healthcare reform that a vast majority of the country is interested. Biden seems to be on that track but Sinema and Manchin are playing hard to get.
