“You are being just like the liberals.”
You are mistaken as to what a sovereign country can do as to its own NATURALIZATION laws.
Drop the Luxembourg discussion if you find it so disgusting. Consider the three-way split that is Ted Cruz. Is he a Natural Born Citizen of even one of the three countries Canada, U.S. and Cuba? If one, which one and why? If one, why not two? If two, why not all three?
He is not a Natural Born Citizen of the United States. Canada and Cuba are not the United States so that would be up to them to decide but it's really irrelevant for our purposes.
