I think those reasons about cover it. There is no benign reason. Someone truly interested would study up and realize that most likely there is SOMETHING wrong, and they would also realize and admit that a “natural born” citizen is not equal in every way to a “citizen”.
I grasp what you are conveying in your post... let me rephrase what you are saying: a ‘citizen’ is not equal in every way to a ‘natural born citizen.’ Makes perfect sense to me, BECAUSE, the framers intended for a ‘n.b.c.’ to be something more than a ‘citizen,’ SPECIFICALLY, regarding the - office - of - President. No mystery. Common sense.
A president with secrets is a president easily blackmailed.
Obama has a lot of secrets.
