About 50 000 Russians in Finland maybe. But if we think about occupied territories...
I take it seriously because it is common opinion that WE have to learn THEIR language and give them more rights than we have ourselves not vice versa.
I guess Estonia was the very corner in SU where Russian language "enjoyed" the lowest prestige among the "aboriginals"
. Maybe Lithuania too, but they have always had less of those Soviet immigrants. Last year in Vilnius neither English nor Russian worked in some places
.
