Well sure, the Democrats could kill the filibuster with a simply majority (if they could get 51 senators on board) but they filibuster a lot as well, to prevent some Republican legislation. So I can see why they’re too pragmatic - or cowardly - to remove it. Not the best source/graph, but a source: https://fivethirtyeight.com/features/why-are-so-many-democrats-considering-ending-the-filibuster/
As for the parliamentarian: they haven’t been removed in a while, and the one before that also served for a pretty long time…I think the Democrats (again, cowardly or pragmatically) are simply trying not to escalate and make the parliamentarian a puppet of the current simple majority. https://en.wikipedia.org/wiki/Parliamentarian_of_the_United_States_Senate
I’m all in favor of nuking the filibuster, mind you: which would make the whole budget reconciliation thing a moot point. but I can understand the desire for some in the party to retain it as a tool. Fat lot of good it’s doing us now, of course.
I think that undersells how uninformed most folks are, and how weak critical thinking skills are, on average. Too many people were credulous when trump said he didn’t know anything about project 2025, and many people currently getting deported believed they’d only deport “hardened criminals”. So I don’t think it’s even being fine with these terrible policies, I think a lot of people were simply ignorant.
The ignorance is by design of course, so I’m not trying to pin the blame solely on individuals: the disinformation landscape is a huge boost for right wing extremism, and of course the Democrats themselves just constantly shit the bed. The Dems aren’t Left enough to galvanize support from people who want real change in the system (so they say “fuck it” and either sit out, or become accelerationists), and even the policies they do tout that would help at the margins don’t get any attention - in part because they’re consistently bad at messaging, but also because nuanced, calm reasoning isn’t as attention grabbing as hate and fear.
