You ignore the posts that made the point of adoption. Adoption is a legal procedure and would have legal consequences.
The omissions have a plausible inference. These are not crackpot conspiracy theorists weaving together a fable.
He has discrepancies in a published online birth certificate.
He has inconsistencies and discrepancies in Selective Service registration.
He has sealed his college records.
He has barred the release of his Birth Certificate.
He appeared with a very few to support a bizarre Senate resolution regarding John McCain’s citizenship.
These things collectively weigh towards more suspicion. If he is for transparency, this would be an easy task to clear up.
Nothing you wrote is contrary to my thinking other than the first paragraph. Adoption by a foreign national cannot remove a citizen’s citizenship. No one can give it away other than the citizen himself when s/he is of legal age to do so.
Nor is there anything in any post discussing adoption which casts any doubt about the inviolate nature of citizenship.
