You don't seem to be able to discuss things without breaking out into insults ("you're stupid" "you're an idiot") ever other post. Come on man, you can do better!
The thing that makes the United States Constitution unique, I would claim are the "Republic of Republics" structure and the Bill of Rights.
Although there are quite a few later Constitutions that copy the later. For instance the Constitution of the Republic of the Philippines has a Bill of Rights. WHat it doesn't have is an enumerated powers section.
And that, of course, is that part of our Constitution that has been flagrantly violated since (at least) FDR, and make me disagree with the idea that we are still a Constitutional Republic in any meaningful sense.
We are a CRINO: Constitutional Republic In Name Only.
You don't know how to edit/preview your own replies either (a repetitive error of yours that I may as well call you on while we're at it).
