“Oh, Really? That other country’s “laws HAVE NO EFFECT [BS] on our citizenship law”?”
It is a part of our laws and court rulings. Your birthright citizenship is UNAFFECTED by any other nation’s laws on citizenship. Dual citizeship is possible.
“Duel citizenship is frowned upon in this country.”
Oh really.

Afroyim v. Rusk, 387 U.S. 253 (1967)
Beys Afroyim (born Ephraim Bernstein in Poland in 1893) immigrated to the US in 1912 and became a naturalized US citizen in 1926. In 1950, Afroyim moved to Israel. He tried to renew his US passport in 1960, but the State Department refused on the grounds that he had lost his citizenship by voting in an Israeli election in 1951. Afroyim sued the State Department, and the Supreme Court ruled (5-4) that he was still a US citizen.
The basic point of the Supreme Court’s ruling in Afroyim v. Rusk was that the “citizenship clause” of the 14th Amendment to the US Constitution — while originally intended mainly to guarantee citizenship to freed Negro slaves and their descendants, and subsequently interpreted in Wong Kim Ark as conferrring citizenship at birth to virtually everyone born in the US — had effectively elevated citizenship to the status of a constitutionally protected right. Hence, Congress had no right to pass a law which had the effect of depriving an American of his citizenship without his assent.
Thus, the court ruled, a section of the Immigration and Nationality Act mandating automatic loss of citizenship for voting in a foreign election was invalid. Other, similar provisions providing for loss of citizenship for serving in a foreign army, or even swearing allegiance to a foreign country, were similarly invalid unless the action was accompanied by an intent to give up US citizenship.
Back to Elg, after she was taken back to Sweden by her parents who renounced their US citizenship, she was reintroduced to Sweden and took on her parents Swedish citizenship, But that did not change the fact at the time of her birth that she was born in the United States and her parents at the time of her birth were US citizens. That's Vattel's law of nation's definition - parent citizens and born in country. Even your link admits that the Elg's case. To quote it, "The Elg case is not, strictly speaking, a dual citizenship case,..."
You do see the difference between Elg and Ark? I'll point that out again. Ark's parents were subjects of China as opposed to Elg's who had US citizen parents.
