This nonsense as you call it pertains to the most important political process our country undergoes every four years and the qualifications of the man who maybe our next president. As Citizens we have the right to know what kind of man we may be voting for or if he is even eligible for the position of president.
And your first responsibility is to determine if you even know what you're talking about. Going on a half-baked theory proposed by a blogger who references a snippet of law is no substitute for doing the research into the law itself.
If you think there's something to this, then do the research. As for me, as I said, the blogger's theory doesn't pass the "smell test" in that it is nonsensical to think that the child of a natural born citizen isn't a natural born citizen simply because his parent wasn't 21 years old.
