I am Czech. Am I a westerner?
A lot of Czechs hate hearing that the Czech Republic is part of the Eastern Europe. The preferred category is Central Europe, after all, Prague lies further west than Vienna.
Since the fall of the Communist regime in 1989, the majority of the population yearned to to finally rejoin the west, and enjoy the freedom and fortune associated with it.
However, during my university studies in the Netherlands (mostly humanities), the notion of western was almost always described with the negative connotation. According to the left-leaning faculty, being a westerner carried a burden of violent colonial history, exploitation, oppression, racism, you name it.
The freedoms and fortunes the west should be proud of were explained as the misfortune of others, the non-western nations. Almost something one should be guilty of.
The thing is that as a Czech, my ancestors took no part in colonialism, and were historically more oppressed than not, whether by Austrians, Germans, or Russians. Yet, I feel pride in values of the west, freedom, individualism, capitalism.
I guess in the Taiwanese context, I am a westerner. White skin, blue eyes, and terrible Mandarin. Not many here would see a difference between me and a Dutch guy.
In the Western context, I do not know.
