"I don’t believe the Founders were stupid at all."Whether they would have approved of it or not is completely irrelevant. They didn't put anything in the Constitution to prevent it.
So you think they would have approved of birth tourism?
“They couldn’t have foreseen the rise in transportation technology that made such a thing possible. But the proper response to such a situation is to amend the Constitution, not pretend that it says something it does not.”
Given that they grandfathered themselves, it is significant that they did not write the constitution to bar this from happening.
Do you know see how your one erroneous assumption is all that supports your other erroneous assumption? Of COURSE they put something into the constitution to prevent it!! You just don't accept the meaning they intended when they put it in there. I can't even give you a case of an obvious absurdity to get you to see how absurd is your theory!
