A ten year old poll, that happened before some important recent events, and is mostly from Russian client states in central Asia and the Caucasus because it only encompasses countries that were part of the Soviet Union is disingenuous, at best, in response to this post about eastern Europe.

Try that poll again today in Albania, Bulgaria, Czech Republic, Slovakia, former East Germany, Hungary, Poland, Romania, and the Balkans. See how that goes.

Edit: I don't know how I overlooked the Baltics, I was just in Lithuania, Latvia, and Estonia for a few weeks this spring. If the museums are anything to go by, their responses to this question would definitely contradict your narrative and they were part of the USSR.
