There's nothing wrong about coming from nobility, is there?
No, but if you listen to people online, you'd think that the entire country was nobility before the war. It's nonsense of course, but that's how people behave.
You're surprised about the negative view of the Russians in part of Europe, well, if you read into the history, you won't be surprised anymore.
I'm not surprised at all, not when you read about who these soldiers were and how they behaved. I've visited all the Museums of Occupation in the Baltic states, and they all make it crystal clear that the Germans at least behaved with some dignity, whereas Russians behaved like animals.
We can't deny that the Russians removed the Germans from Polish territory, but they did it at a tremendous cost to Poles and Poland.
