One thing to mention about this is that the Estonians & co always brag about their knowledge of Russian as soon as they leave the country. They put it on their CV and generally mention it a lot.. I've also heard many Baltic people say that they LIKE the Russian language, litterature and film and that the Russian language training in the USSR days was very good. I don't know how/when/if younger people learn Russian nowadays, but in fact, all Baltic people I know speak Russian - probably fluently. With all that in mind you might think that they might be able to be a bit more open-minded!
I met an Estonian guy today who was a friend of a friend -- and I asked his opinion about this. He said that the real problem was that many of the Russian speakers in Estonia are criminals or unemployed and that they aren't interested in being part of society in Estonia. Since I don't know very much about the situation with criminality and unemployment in Estonia I couldn't say anything in response. This guy said that he personally didn't mind speaking Russian though.
It doesn't help these Russians that the Baltic languages are REALLY strange and probably incredibly hard to learn. They're not Slavic languages and they're not Germanic either... I don't really know what they are. Estonian sounds a bit like Finnish and I am not too sure if I could tell Latvian and Lithuanian apart. I think it would be a really advantageous thing for these tiny countries if they were officially bilingual, like Luxembourg for instance. Too bad they are too narrowminded to think clearly at the moment.
