That's what is strange to me because I don't think "our concept" is bizarre.

To me the most important things to identify "кто есть who" are язык и культура, not blood and race.

Если человек, родной язык которого французкий и который был воспитан во французкой культуре вдруг переедет в Англию и примет английское гражданство then what nationality would he be? What nationality are legal immigrants from India and Pakistan in Great Britain? I think (within the framework of our "Russian concept" ) they are not British, maybe their children will be British though. If they will be assimilated.
