Take a Memo:
You take the "philosophical leap of faith" because I'm sure as Hell am not going to sign on to, "... the point that a baby doesn't have the capacity or obligation to declare allegiance to anything, therefore, must be assumed to be "subject to jurisdiction" by default." That is not fucking the case, IDIOT. BIRTHRIGHT CITIZENSHIP is the case because citizenship DOES NOT DESCEND TO THE CHILD FROM THE PARENTS as I presented to you on at least two separate occasions!!!! The USA is not a fiefdom or a kingdom as it was across Europe back in the day.
No... It's a REPUBLIC with a CONSTITUTION. That Constitution says:
Article 1 Section 8 Clause 4:
[The Congress shall have Power To] establish an uniform Rule of Naturalization.
It doesn't say we're a fiefdom or kingdom where alien babies determine their own citizenship by being born on US soil. It doesn't say illegal alien parents get to decide citizenship based on the geographical location they decide to deliver their rug rat. It doesn't say a stacked liberal nutjob court gets to rewrite the Constitution and decide who is a citizen. And it doesn't say some half-wit moron on a message board gets to dictate who he thinks ought to get citizenship.
This is a plenary and enumerated power of Congress and Congress alone. It's IN the Constitution. It's also IN the 14th Amendment- Section 5.
