To me it's just about what was taught in schools to me, and what I can find on my own. If you Wikipedia Estonia, it says right in the opening paragraph that it is Northern Europe. It's also what was taught to me in schools. Admittedly, being born in '92, I am a first-generation free Estonian and never experienced the soviet union so I don't have any strong feelings of East or the color red, but it is true that Eastern Europe is often talked with the vain of ex-soviet block countries that are corrupt and stuck in time, which is simply not the case with Estonia and I feel just minimizes the work we've done since.
