Well, I can only speak for myself. I'm not just addressing your argument, I'm broadening it. To repeat: I understand what you're saying and it's true -- Reid used it so if he now complains he's a hypocrite. But ALSO: Mitch bleated about it so if he now embraces it he's a hypocrite. We have both parties switching their rhetoric just based on where they stand at the trough, so both are hypocritical.
I personally think the filibuster and super-majority cloture and blue slips and anonymous holds should all be thrown in the dustbin of history. The way they are used isn't protecting minority rights, they allow a recalcitrant minority with no desire or plan to compromise AT ALL to gridlock the government completely. This is particular attractive to a small, radicalized group who believe the more they gum up the works the more their donors can get away with, so they actively attempt to sabotage the rule of law; but even were that not so, you have to have a system where eventually somebody can govern.
When parties were cross-matrixed with ideologies the system worked, but that's no longer the case because ideologies are now completely nationalized -- locality no longer has diversity. There are two solutions: either give the majority more power and let the minority stew, or split the country in half, and let the Eloi live in a country where Dems run against Liberals and the Morlocks run a country where the Republicans run against Libertarians.
(There's probably one other choice: break the two-party stranglehold and let a hundred parties bloom. If you do that you probably also have to get rid of the presidency and just have a prime minister. That to me is even more radical and less likely than a clean Czech/Slovak split.)
