Ethnicity and culture are not static concepts. They change over time. The culture in central Europe, North America, the Middle East etc. 500 years ago looked very different from today. The ethnicity too. People have always migrated and that's part of where ethnicity and culture are coming from in the first place. And that's a good thing.

Nobody talks about individuals or people as arbitrarily interchangeable units. That's a populist exaggeration.

The "natural state" of a culture and an ethnic group is the continuous exchange and intermingling with other cultures and ethnic groups. It's a success of the nationalist right to make people believe that it's the opposite.
