Did the US grew peacefully? I mean all the territory of the United States was taken from Native Americans. Do you get as agitated about this as you are about Russia?
But Native Americans weren't Dutch, were they? Immigrants CHOSE to come to the USA and CHOSE to adapt. A bit different in case of most russian minorities.
If you consider what the Americans did to the natives bad (which you should) you should be as concerned for russian minorities. This "if Americans are bad, we should be allowed to be bad as well" take is tiresome.
Disappearing small languages? I am, but what about it is specific to Russia?
"This "if Americans are bad, we should be allowed to be bad as well" take is tiresome."
Of course it is tiresome. Especially after you say 'American history is good, Russian history is bad' and get reminded about Native Americans. So tiresome!
