On a personal note, I am a first and a half generation American. My mother was born in a part of Poland that is now part of the Ukraine and my father was a first generation American who fought in WWII. My mother did not teach me Polish, much to my chagrin, because we were now Americans. And even though she hated Truman for selling out Poland in the treaties with Stalin, America was her home and we were Americans.
I always assumed this was an American thing, but I guess I can see it from any group that moves to a country they see as "Utopia".
