You are just deluded. No one spoke Belorussian in Belarus before "independence". No one wants or needs to speak it - ever. It has been a useless language ever since the country was taken back from the Lithuanians.

The vocal minority of crazies who want to tout a language that has no utility (and which reflects no culture, despite what they might say) are like the Western Ukrainian Bandera supporters. They're petty, spiteful idiots. Ukraine is finally getting away from that stupid shit, and Belarus never got into it. They should be thankful.

There is no "Russification" of a people who are already Russian. Just like in the Ukraine. Most of the country is Russian anyway. The western fringe was never happy with Russia and never will be. The rest of the country doesn't want to be forced to learn a dead and worthless language that isn't all that different from Russian except that it sounds like how hicks in Russia sound who can't properly pronounce Russian.

My dozens of Belorussian friends don't want to learn Belorussian. Belarus is a part of Russia, period.
