The very concept of nation is quite euro-centric though.
Most of the rest of the world definitely thinks in terms of ethnic and racial groups, and has done so for thousands of years.
I am in the UK, which geographically is part of Europe. That not how we think here and that is a good thing. I don't want our politics to become racialised like it is everywhere else. All it seems to do is bring division and hatred and unfortunately it has imported from America.
If people don't want politics to be racialised, they need to get better at shutting down the blatent racism of the press, police, and major political parties.
Some of it is imported, but the UK is quite capable of its own characteristically British racism, most recently directed against Poles and Romanians.
It may be a European concept but the concept of a nation state is a good one. When it works, it unites everyone as one group. Humans have a psycholical need for a group identity. Better to unite diverse individuals behind a flag, than to form groups based on ethnicity.
