Look at the simple logic of your own quotation.
It contains INCLUSIVE language, and excludes NOBODY, does it?
Yes, such people are NBC’s but it does not say that those WITHOUT two citizen parents are NOT Natural Born if born on US Soil.
So if Ahmadinejad's wife flew to the US and had a child here, said child would be a Natural Born Citizen? I don't think so. It was the obvious intent of the founders to have a Presidential candidate be free of foreign entanglements. It's about allegience.
Two citizen parents, born on US soil = Natural Born Citizen. That's logical.
