I deplore nationalism, but in Poland's case, I would say that it is quite justified, given their brutal history. I can't think of a Nation on earth that has had it quite as bad as the Polish for the last 400+ odd years.
Their fate was especially cruel at the hands of the Russians, which is why the comment about West Russia in the poll is terribly offensive, even to I who am not Polish.
Their nationalism, then, is quite forgivable. Who can blame them for desiring a strong national identity when their entire nation was systematically plundered and razed by the Nazis, all teachers/leftists/intellectuals murdered by the Nazis. Then, just as the Red Army approached Poland, they advised the Polish Underground to rise up against the nazis, and that they would recieve help from the Red Army. Instead, the Red Army sat on their bums and let the Polish Resistance be slaughtered by the Nazis, knowing that this way the Polish resistance would not be able to Oppose the coming Communist dictatorship which Moscow would impose on the Poles. For the next 50 years, the poles would live in a Communist police state.
Not to mention the fact that all of Poland's "allies" stood by and allowed this to happen so as not to anger their WWII allies the Soviets. If I were a Pole, I would hate and mistrust foreigners also.
Whoever made that "West Russia" comment is truly ignorant and should be ashamed of themselves.
