I'm sorry Poland, but you'll always be Eastern Europeans.
The huge political, cultural and economical gulf between East and West is too pronounced.
Whatever silly opinions the notoriously unemployed
Hudsonhicks may diffuse here on the PF, the one about the gulf between East and West seems to be true. This gap exists and it exists more on the political and cultural plan than on any other one. The so-called "social capital" is much lower in the countries of the eastern part of the continent than in those of the western part.
Once I met a couple of Dutch people who were amazed, after having stayed in Gernany on holiday, that the the Wessis were always capable of distiguishing between themselves and the Ossis. And it was not the matter of language, but rather of general behaviour, manners and that something which were not perceived by the Dutch eye, but was obvious for the West German one. In the light of the above, shouldn't the border between East and west be placed on the river Elbe rather than on the river Oder?
Finally, a personal remark: if I myself were to qualify Hudsonhicks to one camp or the other, I would definitely describe him (and some other "Western" members of the PF) as an Ossi rather than a Wessi in terms of culture, behaviour and manners. This means that the true border really runs between our hearts and not our lands.
