1) The filibuster actively disincentivizes compromise and encourages partisanship-fueled, crippling dysfunction.[/url]
I don't understand the logic of this argument. The filibuster actually
ensures compromise by requiring an affirmative supermajority to advance legislation. A majority party that could pass any bill with only 50 votes would never have any reason to compromise, and this is exactly what we see with reonciliation bills like TCJA and ARPA.
2) Respecting minority rights doesn’t mean “the majority party should have zero ability to pass 90% of its agenda, regardless of how popular it is;” that’s called tyranny of the majority and is why the filibuster is something the founders expressly opposed.
Maybe this is a quaint answer, but there's at least some truth in the idea that if Democrats' agenda was *so popular then Republican senators, as well as Democratic holdouts like Manchin/Sinema, would be feeling more pressure from their constituents to get onboard. They don't, so it must be that positive issue polling on discrete, amorphous issues like "voting rights" doesn't actually translate into a workable legislative majority (which should not be very surprising.)
