First off that page is literally titled “About the Topic of Race”, clearly not ethnicity.

And why are you linking to an American census bureau if you want a real one? We all know America uses words differently to the rest of the world.

An ethnicity or ethnic group is a group of people that perceives to be different from out-groups based on shared attributes. These attributes include having a common language, culture, common sets of ancestry, traditions, society, religion, history, or social treatment.[

Yes it is.

You’re describing your friends genetics or ancestry being different to their ethnicity or culture. Asian or White are not ethnicities.

Ethnicity is not ancestry or “race”. And yes I know Americans like to call different looking people ethnic.

They largely are, ethnicity is culture (tradition, language, customs, beliefs) and history.

I do not relate culturally to the people where I live, I have far more in common in beliefs and values with the typical terminally online compared to people where I grew up. And I’ve been online since the Internet started, so I’ve got the history too.
