For a comparison calling Russophones of the regions settled in the last 200 years in Siberia, central Asia, Caucases , Transnistria as calling Americans, Canadians, Australians – Anglo-Saxons.  They speak English having historic  connection to England. But they are not Angl-Saxon. They  have mixed origins. So they are English because they speak English?

I am not sure if I chose a good example to explain what I mean.
