Excellent question.
There is certainly no shortage of natural born citizens who hate what is good about this country.
Case in point: Zero's neighbor
and probable ghost writer, Billy Ayers!
The point of the natural born citizenship requirement was, and is, to ensure to the greatest degree possible the presumed loyalty of an aspirant to the office.
If "Obama" is telling us the truth about his origins (which he very well may not be, since no definitive proof has been offered to date, one way or the other), then his even potentially divided loyalties deriving from the foreign citizenship and transitory nature of BHO Sr's sojourn in the US would make Barry a citizen of a type other than Gold Standard (Natural Born) Citizen. That being a citizen not requiring the force of manmade law, including the 14th Amendment, to make you a citizen.
There were necessarily naturally occurring citizens prior to the 14th Amendment, and didn't require human law to render them citizens. They could not be anything but citizens of their country, because they were born there, and of parents who themselves were citizens. This shouldn't be difficult, and yet you fail basic logic. Again.
Now tell me once more how I'm circling the wagons. Heh
