The cynicism is uncalled for.

The culture of places are not so well defined in America. It is a new nation of immigrants. Europeans may have lived in the same towns for hundreds or thousands of years. American is less than 250 years old.

Americans identify as individuals. An individual is identified by personal accomplishments or work. Alternatively, a group identity might define a person by location or family name. The root question "who are you?" is asked depending on what approach you take. Identity is a subjective social construct; neither approach is more right than the other.
