Another thing, keep in mind that our Founding Fathers rejected putting in a common law citizenship into our Constitution. They were trying really hard to get away from a system in England in which anybody born within a king’s realm is subject to the king’s authority -— for life. In other words, they were letting states decide citizenship. Of course, that changed with the 14th Amendment.
Another thing is that no other nation at the time had an anchor baby law on their books for citizenship. So surely if that’s what the 14th Amendment authors intended, and what Congress passed, and the states ratified, they would have made sure the amendment’s text explicitly stated so. For example, the 13th Amendment’s text makes it very clear they were prohibiting slavery, including different forms of slavery that many people at the time didn’t consider slavery (indentured servitude). At the time the abolitionism of slavery was relatively new in just about anywhere in the world except the Anglican nations. So they had to make sure the 13th Amendment’s text clarified that they were going against the norm.
Surely the leaders who ratified the 13th Amendment with that detailed text would have wanted the 14th Amendment to have equally descriptive text if they were going to violate the norm of other nations.
This is all a bunch of dorm-room lawyering ... I’d really like to see this issue settled definitively, by people with actual authority.
