The point of the critique is that otherwise reasonable processes can quickly become unreasonable when bad actors become involved in the process.
Bad actors are famously good at finding where processes do not scale, and then overwhelming those processes in order to grind things to a halt.
See:
- the filibuster (60-vote threshold for cloture motions)
- a speaker refusing to allow votes on legislation that would pass with overwhelming margins (currently, Ukraine aid and border bill)
- vote-a-rama which usually serves no purpose except to trigger recorded "gotcha" votes that are completely unrelated to the reconciliation bill and drive eventual final vote to a stupid hour of the morning just to troll colleagues - see literally any of Tommy Tuberville's amendments
- motion to vacate: renders half of the Congress into a mode where the only thing they can vote on is a Speaker, and if the past is prologue, this mode will last for days / weeks. No other legislation can advance without a rule change, which would require a vote that probably wouldn't pass due to the obstructionists wanting to obstruct. I'm honestly surprised that the gear-grinding caucus hasn't tossed Johnson out on his ass and then just vote 'no' to every speaker nominee and rule change just to stop literally everything. Not sure if it also stops committee hearings, which is why they may not have done this - can't have sham [impeachment|weaponization|hunter biden] hearings to step on garden rakes in and we can't have that!
- lawsuits, and getting judicial stays pending ridiculously long legal processes
- appeals of lawsuits, and getting judicial stays pending ridiculously long legal processes
This is not an exhaustive list. And people wonder why government can't get anything done.
