Ah Poland. Europe's punching bag.
That's also why it doesn't make sense to talk about white and black culture outside of USA because the cultures are so different from country to country in Europe and there's a pecking order going on amongst white people. Even people from, say, the Middle East will rarely say "You white people" but rather "You French/German/Norwegian/and-so-on people"
Now, is it racism? It depends on how much you buy into the idea of race. A Dane who hates Swedes wouldn't call that racist, but people from Eastern Europe start to look different enough that it's often called racism, and in a way that plays into the negative feelings too. It's complicated.
