I know this is difficult for people in Europe to understand. And they hate it when a US tourist goes to visit x country and says “I’m x”.

We never really had a unifying cultural identity as pretty much everyone was immigrants. (Except of course for Native Americans, but their culture was basically eliminated.)

This is why we have terms like African American or Asian American or Irish American. When a black person moves from Africa to England, they don’t call themselves “African English”, they just call themselves English. A lot of this has to do with the power structure which separates us and the underlying racial hierarchy imposed by the ruling class for two centuries. Most European countries do not have this same level of diversity. And whatever diversity they have, the reasons for it are very different.
