All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.
The "Western world" includes the US. Please provide an example wherein your doctrine regarding article IV has been followed.
Is that how you propose we decide what our law is, by what the rest of the world does instead of what our Constitution says?
"Our law" is based largely on English common law. Our constitution has roots in the Western tradition. Your reading not only ignores all historical Western precedent, but even American precedent, the dictates of the framers, Interpretive works by American experts, and the Constitution itself.
I prefer the Constitution obviously.
You appear to prefer #3Constitution, which does not exist for the remainder of the 279,999,999 people of this country. We are not bound by your inane interpretation of the document (thank goodness). Certainly the men of the South 140 years ago were not either.
