Which is what I said. They want the shutdown more than they want to do anything that they have to use to stop it.

Well, that's a little different than just saying "They must want the shutdown." They might vigorously not want the shutdown but loathe the idea of destroying the filibuster even more. In that case, they don't want either of them.

That's in contrast to an argument that they actually might want to have a shutdown - not that it's the lesser of two unwanted options, but one they affirmatively want to have happen. One can certainly make that argument, and some have. But I think there's a differentce.

To give an example, Democrats want due process rights to be followed in the criminal justice system. An unavoidable consequence of due process rights being followed is that more guilty people will escape punishment for their crimes - at least one person will escape justice on a technicality that wouldn't otherwise if we ignored due process rights. But I think we would all push back on a claim that "Democrats want some criminals to escape justice," even if the person making the claim agreed that they just want the criminals to get off scott free more than they want to do anything to stop that from happening.
