anyone who cannot swear complete allegiance to the US Constitution, must be stripped of/or denied US Citizenship and deported from this country. period.
So let's examine the oath taken to attain US citizenship that is also implied if you are a natural born citizen:
"I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the Armed Forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God."
The Constitution supersedes all other allegiance if you are to be a US citizen. Don't want to do this? Get out!
