Those that wrote the Constitution were grandfathered in... There was NO question regarding their loyalty.. It was a protective measure to the 'natural born' citizenry in future generations. It was/is a birthright. You know kinda like Esau who sold his birthright for a bowl of red pottage (lentils)...
I was born in Germany, of two US citizen parents... born a US citizen YES, but NOT natural born.
By your own claims, regarding “natural born” intent of the framers, a child born on US soil to illegal aliens is eligible to hold the office of the president, but a child born in another country to a member of our military is not eligible to hold the office.
That is a very silly position. Hence, the snark and sarcasm.
