Uh, no.
The ratification of the Constitution( of which the 2nd Amendment was a key) was upheld by SCOTUS in the cases I cited.
The US Constitution was ratified on June 21, 1788.
The 2nd Amendment (which was the 4th one put up, not the 2nd) was proposed on Sept. 25, 1789, along with 11 others. It was not ratified until Dec. 15, 1791, nearly 3 and a half years after the Constitution.
No, the subsequently enumerated 2nd Amendment was not key to the ratification of the Constitution.
Please explain why there is a Bill of Rights.
A Bill of Rights was required to be submitted at the 1st Congressional session, Ward, or a few of the states might have refused to ratify the Constitution. Might!
Without the Bill of Rights there would be NO Constitution as written by 1789.
It's a fine claim, Ward, with zero evidence. Back to usual.
But even if we were to accept that at face value, which we don't, it
still isn't evidence that the 8th proposed amendment, 4th amendment passed by Congress, and 2nd Amendment ratified by the states was "key" to the ratification of the Constitution.
It isn't even a suggestion of a connection!
But you are simply wrong. The first 6 states to ratify didn't give a damn about the Bill of Rights. (PA had folks who cared and tried to block a vote, but their only way to do that was to block quorum - they were not substantial enough in number to block it should it come to a vote - and their attendance was forced upon them and they were locked in.)
Massachusetts cared. But when John Hancock shifted his position from anti- constitution to pro-constitution, that ended that. Why did Hancock shift? Because he was promised that certain amendments protecting individual rights were going to be considered by the first new Congress.
Key word? CONSIDERED. Not accepted. Considered.
New York created a long list of assumptions and with it recommended amendments, by far the largest of the lists of recommendations. It was quite something, Ward.
Oddly enough, not only were most of those recommendations not among those passed by Congress, let alone ratified by the states, but your pet Amendment, while mentioned under assumptions, did not make the cut for recommended amendments!
