The law itself says it applies to people who are citizens at birth.
Where does the law say that? Can a law apply to a person who isn't born? How is that possible?
No, the law is applicable upon certain children at birth. It "applies to" alien parents.
The speed limit through a residential district is posted at 30 MPH.
Upon whom is the law applied to? Is it applicable upon another?
“It’s saying, ‘Hey, driver, the speed limit is 30 MPH. If you don’t want a ticket don’t speed. If you do a fine will be levied.’
In other words...If you’re here legally and you have a child here they’re going to have U. S. citizenship whether you want them to or not.”
That’s what it says to the parents. What does it say to the child? That if his parents meet the criteria, it is a citizen. Why are you restricting yourself to the parents’ perspective? The law may not be comprehensible to the child, but it will control his future, and therefore does apply to it.
“Where does the law say that? Can a law apply to a person who isn’t born? How is that possible?”
That isn’t possible. It can, and does, apply to people upon being born. Apparently you think that because they can’t read it and be advised of consequences, like the parents, before being born, it somehow doesn’t apply to them. But you don’t have to read a law for it to be applicable. That’s why ignorance of the law is no excuse. It’ll apply to you whether it’s said “Hey” to you or not.
Your argument, as far as I can tell, is that a law that begins "The following shall be nationals and citizens of the United States at birth" does not actually "apply to" those people but rather "is applicable upon" them. That's a rabbit hole I don't care to follow you down. Do let us know how it works out when you explain to the cop that the speed limit doesn't apply to you, it's just applicable upon you.
