Great, no problem with that.
So the problem isn’t with dual citizenship per se with what constitutes a natural born citizen, correct? Because this thread was all about how having a dual citizenship disqualified you for the Presidency. And I think we’ve reached agreement that you can be a natural born citizen AND hold dual citizenship.
The POTUS eligibility issue is whether there is dual citizenship at birth from a foreign citizen parent or by being born on foreign soil, not dual citizenship aquired as an adult or from a previous citizenship of a parent or grandparent. SCOTUS has only ruled that there is “no doubt” that the child of two US citizens born on US soil is an NBC. SCOTUS has only said there “is doubt” over the child of only one US citizen parent and foreign parent born on US soil.
The founders were fully aware that other countries, like Britain, could claim as subjects the blood children of former citizens (War of 1812 fought over impression of US NBCs claimed as UK subjects) but appeared to disregard that type of dual citizen from being qualified as NBC (nearly the whole USA in 1800).
After reaching majority an NBC can obtain foreign citizenship in some cases without renouncing US citizenship and thus an NBC can become a dual citizen as an adult, but that has no bearing on NBC POTUS eligibility, which is a condition of birth that cannot be altered.
