Real Americans do not hyphenate themselves no matter where they were born.
Except for the Irish who celebrate Irish festivals, wear ‘Kiss me I’m Irish’, etc.
Except for the Italians who pride themselves of being Italian in culture, food, mentality, etc.
Except for the Greeks who have Greek festivals throughout the U.S., movies, events.
Course all of us are Americans point of assimilating. I think Iranians have mixed better than the above.
