Why is it wrong? It is a fundamentally American concept that we do not punish children for the actions of their parents, at least not by law. Legally-speaking, the motivations and behavior's of a kid's parents make no difference when it comes to whether that kid can run for President someday.
Correction from me as I stated it wrongly. I believe if two come here from another country and become citizens BEFORE they give birth to there child, then their child is “natural born”. :)
