It IS as simple as I say, but as usual, the Constitution has been ignored and subverted so that what is patently obvious (the 2nd Amendment) has been twisted in a way it was never meant to be.
You're the one ignoring the Constitution and trying to trample the will of the people and their elected representatives that passed the 14th amendment in 1868. I don't care what some French guy named Vattel said. He certainly wasn't natural-born. The 14th amendment grants citizenship to everyone born in this country. There are only two types of citizenship - born and naturalized. Jindal wasn't naturalized so he's a born citizen. Obama wasn't naturalized so he's also a born citizen. Being born here trumps any writing you can come up with and all court decisions regarding the 14th are IRRELEVANT. The Constitution trumps everything. It's the ultimate authority on citizenship. Nobody outside of the birther community cares about the secondary source, persuasive crap being put out there.
If you are born in this country, you are a citizen. If you don't like that fact, repel the 14th. But the attempts of birthers to get around it seem downright seditious sometimes.
