There's a wide grey area here. Some people who are born and grown up in a country don't see themselves as a native, and others who come to a country sometimes do. It is clear that many bend things round to accommodate their preconceptions and understanding of words. This is largely based on some intangible patrimony they believe only they are proud enough to deserve. Even stricter definitions will not cure this ageless malady of the human condition.

Sprichwort:
Dummheit und Stolz wachsen auf einem Holz
