I am American & most of my ancestors are from Northern & Eastern Europe, some dating back to the 1400's.
I consider myself 'other' (race) Euro American.
So I really love food from around the world.
Most Americans, only consider themselves 'American'. Because most have soo.. many nationalities, that their ancestors blended into 'one culture- American'.
Americans tend to be 'nomadic'. I have lived in 13 places & have family in 5 states & other countries.
Most Americans are 'Nationalists', not 'Globalists', So no matter what or who we are, even if it is a separate community lifestyle, or state, we are still 'One Nation'
Where I live there are many races & nationalities & 2 main religions. There are 5 dialects of English in my state. I have lived in this state for approximately 3 years & one dialect of English, I still can not understand...

Hhhaaa..
I apologize to them a lot, because they were born in this state & I was not. And yes..when I speak they can tell....hhhaaa..
Accents are easier for me, for some reason. Perhaps because I grew up hearing so many. But American English dialects..
(Are regional) Ugh.. There are hundreds!
