You apparently have not read the actual case of The Venus, not surprisingly, either that our you do not understand what it says. It is much about citizenship as an essential element of the controversy between prize claimant and defendants.
Either you are extemely dense or just stupid. First you cite something Cicero said about the Roman Re;ublic as if it were English common law and then you engage in disinformation by saying that I said, which I did not, that the French invented the term "citizen" at the time of their revolution. As you pointed out it goes back to Rome and classical Greece. You may have heard of the Latin word "cives."
You seem to be historically quite ignorant. Let me point out that the great struggle at the time of our Revolution was between republicanism and monarchism. Under monarchies the law discussed "subjects" as in subjects of the King as lord, dating back to feudalism. By contrast we and the French revoloutionaries looked intitially, before the excesses of the French Revolution, upon ourselves as fellow republicans in an otherwsie monarchistic world, as citizens of a Republic, like all those that Madison studied under Witherspoon and of whose demise at the nands of demagogues and foreign influences they were quire keenly aware and very concerned about. That is the point, which you seem to assidiously miss and misrepresent. It is kind of like misrepresenting that the ancient Roman Republic concept of citizen of Rome is a term of English common law of the 1700's.
Is it beyond your comprehension to see that Marshall was precisely, in the quote from Vattel that he used, quoting Vattel's concept of being a "citizen" who is natural born in the sense of being the child of a citizen father and mother? Perhaps you have dyslexia and cannot comprehend phrasing that means the same in more words than the more concise "natural born citizen."
You seem to take pride in trolling for those who would destroy our Constitution and doing it with such lack of comprehension and delight in misinforming. History will expose the fraud for whom you troll. You must be concerned that he and his Ci-cago gang won't be able to use you and others like you to destroy the Constitution and that it will not only be saved but will save the day as it was designed to do, against essentially foreign influences and demagogues who can, at least temporarily, stir up the masses.
