a. The birther movement is right...and everybody else is wrong, including all those people whose business it is to know what's in the Constitution. Or...
b. Happersett never has been recognized as the definitive last word on "natural-born citizen" and the whole movement has been built on a false premise.
So, which is it?
You are attempting to present me with an argument called "the fallacy of false choice." You limit my answers to "either or" with the implication that there are only two answers, when in fact there may be another answer.
You are also presenting me with the fallacy of "argumentum ad numerum/argumentum and populum", as well as the fallacy of "argumentum ad verecundiam" I'm not going to bother answering fallacies.
Numbers don not prove truth. Popularity doesn't prove truth. Authority does not prove truth either.
Do you know what proves truth? Evidence. The evidence indicates that the Country has been badly misled by British Trained lawyers, (several of who wrote books) and by a mis comprehensions of the intent of the founders when they created article II.
So, as I posited in one alternative, your answer boils down to an assertion that, for over 200 years, constitutional scholars, lawyers, jurists and experts have been mistaken and it is only the birthers who have discovered the truth.
Isn't that about it?
Okay, whatever you say...
