I'm sure these hyphenations exist in every part of the World. It's these hyphenations that make a Nation stronger IMHO. In India, we have Luso-Indians (or Portuguese Indians), Dano-Norwegian Indians, German-Indians, French-Indians, Chinese-Indians, Parsis (Persian-Indians) etc. who made India their home. We don't force them to call themselves only "Indian". Why would you want someone to sever their past and their rich cultural heritage just to prove their Patriotism? Isn't that against the very notion of a "Free country" / "Republic"? As long as the citizen is not involved in any anti-National activities (terrorism, hate speech, espionage, disdain/disrespect for the Country's laws etc.) there is no need to bring that citizen's loyalty under suspicion.
There is no measure with which one can "feel more sympathy" for their ancestral-country than the country for which they have accepted citizenship. "Feel more sympathy" for what? Would an adopted child "feel more sympathy" for it's biological parents than the parents that nurtured it?
