Immigrants have gone through incredible emotional struggle to adapt to a new culture. They are not a reliable source to assess how things are in their country of origin, especially not how things are currently. And to lump together Russia and Ukraine and say that things are not getting better, is gross oversimplification. Ukraine has had weak leaders and strong oligarchs since the fall of the Soviet Union. However Russia has had strong leaders (Yeltsin and then Putin) who have consistently pushed back on their oligarchs. In particular Putin has spent most of his leadership period fighting corruption, reigning in oligarchs, and undertaking the perestroika (redevelopment) that Gorbachev was never able to achieve. Things in Russia are getting better while things in Ukraine are getting worse. They are heading in opposite directions and many Ukrainians are aware of this which is why public dissent has been growing there.
Being offended at someone's assessment of a situation is a political statement. We should not be surprised to hear people making political statements about a political situation. None of this makes one person more right or another one more wrong.
Politics is very hard to figure out, and we should all be careful of making oversimplified statements. It's not as simple as Ukraine signs an agreement with the EU and then everything is rosy. Neither is it as simple Putin twisting Yanukovitch's arm. This is a bloody complex geopolitical problem and Ukraine is getting no support in solving it from anyone outside Ukraine. They have to work through it, accept the hard knocks, and ultimately reap whatever benefits that their decision brings. Cheerleaders on the sidelines have no skin in the game.
