Thank you for you kind words. Here following is the link to my article on Euler Diagrams to prove the truth or fallacy of an argument, and its application to the constitutional term (and specific kind of Citizen), “natural born Citizen”, or to parse that ... “natural” (that is by Natural Law) “born Citizen”. It is a subset, the largest subset, of those Citizens who are “born Citizens”, i.e., the largest subset of “Citizens at Birth”. See this article and Euler Diagram for more details: https://cdrkerchner.wordpress.com/tag/euler-diagram/
