I would guess that it is much more difficult to extradite a person to the U.S. from another country if that person is a citizen of that country, regardless of whether they hold U.S. citizenship.
It seems to me that the whole point of singling out one single office in the country for special treatment has a meaning. I propose that meaning is to reduce if not eliminate persons from holding that office who might have divided loyalties. If a person's mother is a British citizen and that person's father is a German citizen, then it would not surprise me at all if the person himself felt loyalties to those countries.
I have one grandson who has dual citizenship. His mother insists that he is eligible to be President. I do not.
To those who think it would not be "fair" to eliminate Obama or Kamala from eligibility to be President, I think you need to consider whether it is fair to 300 million citizens to introduce doubt about the loyalty of a President.
I don't understand why you think your birth circumstances determine your values.
By your logic, if your parents had moved to Germany or the UK when they were one, grew up there and indoctrinated you in the glories of those countries they wouldn't necessarily be a threat.
On the other hand, if your parents left Germany and decided the US was a better place to live, emigrated here and raised you to love this country you're still unreliable by virtue of German law which says you're a citizen.
You're letting German lawmakers determine who's eligible to be President.
