Did you read the whole thing. Because tnaturalization is discussed at the link. The intent of the Fourteenth Amendment was never to confer citizenship by birth to those children who were born to parents who held allegiance to a foreign country.,
Well then that's how they should have worded the amendment
I read the piece and the author does a poor job of supporting his argument. He quotes Sen. Howard who states:
"This will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of ambassadors or foreign ministers accredited to the Government of the United States, but will include every other class of persons."
He's saying ambassadors aren't subject to US jurisdiction so their children born here wouldn't automatically be citizens.
No one disputes that.
The author tries to extend that restriction to any non-citizen parent, but was unable to provide any support for that contention.
