You are misreading. Do you say that Japan and S. Korea are part of the West? Certainly "Westernized", but not "West", given the different history and cultural traditions. One example is religious differences like Shintoism, but there are many others.

I believe the argument is that Nigeria should be seen the same way. While Westernized, to place it under the category "West" also serves to minimize its own long historical and cultural history which is independent of the European tradition.

If you say that Japan is part of the West, then I can agree that Nigeria could also be part of the West, but disagree that it's a useful categorization. We have other terms, like "industrialized", which are less culturally burdened.

Otherwise, Nigeria is not part of the West in the same way that Japan is not part of the West.
