Their conclusion is simple - Poland is a land of racists, whiners, idiots and incompetents. Poles caused pretty much all the worst wars (thanks god Germans stopped them), kill Jews for a hobby, expel Germans, don't know their own language and on top of it they put ketchup on their pizzas. Oh, and they smell and about the only achievement they have is kielbasa.
That stereotype is... somehow I feel I have heard it somewhere, just don't know where. Maybe Harry? No impossible he is a nut but he knows how to behave?
