RE: Read a history book.
Which one?
I DO READ HISTORY BOOKS, None of them ever tell me that the framers insisted that a Natural Born Citizen is someone whose parents MUST ( emphasis ) Both be born in America.
There's a reason for that. The birthers hadn't made it up yet.
Then I guess you missed my point entirely. The whole both parents thing is absolutely ridiculous birther mythos. I was pointing out that you have to look at law chronologically. The rules that the framers established for citizenship are not applicable today, except as they are taken in context of the amendments and the Supreme Court rulings from then to now. And if you are curious enough, you will certainly find that suffrage was reserved to land owning white males and rules were established by each state some of which included religious rules (i.e. Jews).
