Strawman. He/She never said that the Democrats' abuse wasn't uncalled for or unprecedented. The poster simply stated that "not required" does not equal "prohibited."
It doesn't have "some" merit.
Yes, it has "some" merit, but very little in the current conversation. While I made a subtle distinction between the ideas of "unconstitutional" vs "extra-contsitutional", I think it is way past time that the GOP called these idiots on this imposition by a minority in the senate of a supermajority requirement that is clearly outside the scope of the few specific items where a supermajority is required by the Constitution. And while "not required" is not equal to "prohibited", neither is "not prohibited" equal to "authorized upon approval of a minority".
