I looked it up and think the wiki has done a good job of explaining.

The concept of Western culture is generally linked to the classical definition of Western world. In this definition, Western culture is the set of literary, scientific, musical and philosophical principles which set it apart from other civilizations. It applies to countries whose history is strongly marked by Western European immigration or settlement, and is not restricted to Western Europe. Much of this set of traditions and knowledge is collected in the Western canon. [4] Various uses of the concept of Western culture have included, rightly or wrongly, critiques of American culture, materialism, industrialism, capitalism, commercialism, hedonism, imperialism, communism, Nazism, fascism, racism or modernism.

It is and always has been a generic term that was never meant to be used to classify a specific culture.
