Already did, last April (non-seq loses again). And your claim about the Confederate judiciary not being formed (yet again).
You sound like a desperate lawyer trying to convince a jury when his case doesn't have a leg to stand on. You are the one making a claim for which you have no evidence.
Single-line throw-away is your characterization, not mine. Let's look at some singles lines.
"Mr. Gorbachev, tear down this wall!" This single line came in the middle of the speech, but what the heck.
"From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent." That's about 2/3rds the way down. That far enough for you?
"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." That's about 3/4th the way down.
Single lines can be pretty effective. Those above were more moving and more effective than Davis' one-line call for the Confederate Congress to do its duty, but you can't dispute that Davis said it. Case closed unless you can find where Davis argued against forming the Supreme Court. Psst, the ball's in your court. Been in your court for a while.
If backed up with actions. But there is no evidence at all that Davis did that. Reagan backed up his words with actions by winning the Cold War. Kennedy backed up his words with massive funding for NASA. Bu Davis? He did nothing, nothing at all, to promote the establishment of a supreme court. He was more than happy to allow the senate to violate the constitution and didn't mind at all not having another branch of government to answer to.
