Most of Europe and the world don’t have as wide ranging protections for free speech or bearing arms as we do, either. So using that as an argument is not relevant, regardless of any spiffy smart sounding Latin phrases.
The text of the 14th amendment follows:
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
For better or for worse, the amendment does not make any exceptions for denying citizenship to persons born of late term pregnant women who just arrived on the shores.
Marking lawful citizens as enemy combatants for simply being born in the US sounds like a very bad idea to me, and should be to you too. Why would I not be a potential enemy combatant for making this comment on hacker news right now?
