Yeshu: Obsessive martyrdom complex.
If you read Polish history you would know that we had it rough. From backstabbing allies to having the entire country erased from the map for a 100+ years.
However, instead of learning from this and growing as a country we blissfully bathe in our tragic past like a emo high school girl that constantly complains how her life is shit.
So Instead of pulling ourselves together we complain how bad we had it in history as if to gather other peoples sympathy.
To give an example, a few years ago there was a plain accident in which the former president of Poland died with some other important political figure heads while flying to Katyń, a famous historical landmark where the Soviets executed allot of Polish soldiers, politicians etc. It was a big blow. But instead of sorting the thing out the media keeps milking the event to this day. It even went so far as renaming it from the the Smoleńsk Tragedy (the town where the plain fell) to the Smoleńsk Massacre as there are allot of conspiracy theorists claiming that it was a secret Russian attack.
LOOK AT HOW BAD WE HAVE IT!!! PITY US!!!!
Poland, historically, Polish-Lithuanian Commonwealth has massacred pretty huge amount of nations around it. In typical medival conquest wars.
Also, Soviets != Soviet government and especially !=Soviet Secret Service, especially in 193x and 195x (Beria, Yezhov and co), which can be best characterized as strategic "mayhem".
You simply can't connect them to world view of common people (Soviet citizens) or even regular Soviet army (which, like any army, executes what its commanded to).
The soviet special service did no genocide on basis of nationality, but plenty of genocide on basis of political views. Pretty much anyone opposing them would be executed or punished. Government brutality, which every country on this planet had at least once, in its history. If you think its not "democratic", not "western", take a look at US confederates or slave trade/colonies of Great Britain. You can't mix all people in one basket.
