Just declare that kids born to illegals are not subject to the jurisdiction of the United States, and that removes any thought of 14th Amendment citizenship. We still have to worry about what to do if those kids later commit crimes, but at least they can’t claim citizenship so we can declare them persona non grata.
14th amendment citizenship is a myth. The 14th states that if a person is born on U.S. soil and has allegiance to(subject to) the U.S. then that person is a U.S. citizen.
The 14th amendment myth is just another liberal way of rewriting the Constitution.
That such declaration is even necessary is the result of a legal myth.
The words "subject to" have no meaning when used in the 14th A if they are not understood to mean "exclusive jurisdiction" which they were at the time. That is because every human within the U.S. is subject to the jurisdiction.
Illegals may immediately go to any Mexican (or other) embassy and be recognized as citizens and receive all manner of relief. Thus, they are not under the exclusive jurisdiction jurisdiction of the U.S.
