It is abundantly clear, from both the historic record and the legal definition of the term "subject" contemporary with the date at which the 14th Amendment was drafted, that children of aliens are not "subject to the jurisdiction" of the United States. They are instead WITHIN the jurisdiction of the US. They are not citizens of the US.
That the 14th Amendment circumscribes who CAN be a citizen, and the fact that the Constitution is a limiting document that disallows anything it does not enumerate, means that Congress MAY NOT confer automatic citizenship on anchor babies. They must be naturalized as adults.
The burden of proof, as has has been placed upon people who oppose existing policy, in fact belongs placed upon those who advocate for it.
yeah, free for you, out of my pocket.
