The first two points it makes is that we are living under admiralty law and admiralty law is the same thing as martial law. This does not follow at all from the constitutional citations given. Admiralty law is the body of law pertaining to the seas and rivers, which is delegated to the federal government under the Constitution. Martial law is something entirely different.
If that were not crackpot enough, the post implies there is such a thing as an Article IV judge, which there is not (there are only Article I and Article III federal judges) and that Article III judges do not have jurisdiction over claims made under Article IV of the constitution, which in fact they do and have exercised constantly throughout the history of the country.
The real crux of the argument seems to be that because the state of Nevada was formed, the land which belonged to the federal government must of necessity have been transmitted to the state of Nevada, or the people of Nevada, or somebody else. This is also a crackpot argument, in my opinion, because the quoted sections of Article IV of the constitution explicitly state that federal government has the right to own land and make regulations concerning that land, even if that land is within the boundary of a state.
Since we're talking about him, might as well ping D Joyce to the conversation.
Go back and re-read Article III Section 2. Nowhere in that statement is there any reference to jurisdiction over citizens within a state. Such citizens are accorded jurisdiction as listed in Article IV Section 2. The Constitution recognizes that each state is a self regulating agency, and governed and supported by it's citizenry. The only times that the Federal Courts should become involved is where the jurisdiction crosses state lines, or involves a constitutional restriction.
Seems to me that the difference between us is that you see the constitution the way they teach it in the Government Indoctrination Centers; as providing the government with permissions to act. I, and most here, see it as restrictions against government action. My government glass is half full, and I want to drain it some more. Your government glass is half full, and you want it filled up. Well, I am proud to say I side with the boatloads of terrorists that fought against my Royalist brethren, and give thanks I was able to join them, albeit a few years later.
