"Filibustering is a valid process. Blanket blocking of an up-or-down vote for any nominee is not. It's abrogation of their duty"

Filibustering is a valid process. Then you would agree reading "Cat in the Hat" for hours on the Senate floor is not obstructionist, but is instead a "valid process", right? Or does your opinion change if you agree with who does it ?

As mentioned, I agree Garland should have come up for a vote at least. No argument there. However, a filibuster is just as obstructionist as not allowing a vote at all. Both are "valid" processes, as distasteful as they may be to the group on the opposite side.
