Your grasping at "citizenship" is a classic misreading of the Constitution (and law), and a misunderstanding of the rights guaranteed therein. The issue is not "citizenship", but whether the individual involved is a person within the jurisdiction of the United States. There can be no denial that a human with distinct, individual DNA is, in fact, a person. Go back and re-read those documents again with an understanding of "person" and not "citizen" being the issue.
