No citizen of one country is a member of the territory or sphere of authority of another country. One may visit, but that visit doesn't make you a member of that society. That is why there are embassies and passports... to service the citizens of foreign sovereigns.
Your argument, and the argument of all jus soli proponents is one of schizophrenia... in making the argument that location of birth--and not the allegiance of the parents--takes precedence, you undermine the rest of international law and authority. Foreign diplomats who have children while on duty in our country are not birthing US citizens. The same is true of those who illegally enter.
Correct, but I have never asserted that point. I would point out that while in another country, you are subject to the jurisdiction and laws of that country. That is an established fact of both US and international law. I have traveled and worked in many other countries and have have been subject to their laws.
My argument is NOT jus soli. My argument is the current reality and jurisprudence. Trying to redefine the meaning and playing word games is not what is needed here. Change the 14th ... and I fully support changing the 14th.
