If you are from a scientific background as you say....then you should be asking “why” and not just “what” and so on. For example, do you know WHY the NBC clause is even included in the Founding Docs?
When you ask and answer that question, you’ll have your answer.
I have read extensively on this issue because I really hoped we could avoid Obama. Rather than attacking my understanding why not ask why you need to settle this without having the facts.
