They clearly stated in the amendment that it was for people who fall under jurisdiction (i.e. freed slaves). Foreigners do not fully fall under jurisdiction, they are only in jurisdiction insomuch as they are within our borders. These people have citizenship elsewhere. They are not American citizens because of that amendment.
I just posted what the man who wrote the fucking amendment said. He explicitly said it does not confer citizenship to aliens simply for being born here. Magic soil was a "right" manufactured by an activist judge. It's never been tested by SCOTUS, and I bet when it does you will get a 5-4 ruling in favor of being fucking honest about what the Constitution says, and we can start shipping these people back to their real countries.
You don't have the Constitution to support your genocide. Genocide is disgusting, by the way.
