No, you are wrong and the language of that repealed naturalization act reflects that, they said “shall be considered as natural born citizens”, which clearly indicates they were not.
Yes it was repeal but it was ALSO replaced. And that act was repealed and replaced an so on and so forth till we get to the current legislation. And those laws define who is a citizen at birth and does not need to be naturalized.
And if they “shall be considered as natural born citizens” - does that not mean they have all the rights, privileges and responsibilities of a natural born citizen?
Just curious.
