I think you hate being reminded of Biden starting the whole thing. Partisans hate being reminded of their hypocrisy.
These explain why McConnell's precedent was different:

And this explains the irony that nominees by Republican presidents with Democrat-controlled Senates resulted in 15 hearings and 15 votes and 12 confirmations, whereas nominees by Democratic presidents with Republican-controlled Senates (the only example in recent history was, in fact, Obama's nomination of Garland) resulted in 0 hearings and 0 votes and 0 confirmations.

Edit - I also notice that you declined to address McConnell's new precedent to set confirmation at 50%+1 votes rather than 60.
