I know this is a bit petty, but I've stared to resent a little that even though I'm Mexican, I'm not considered Western. What am I, then? Eastern? Central? Southern? I'm not just arguing about the geography, but about the culture. I feel much more like a Canadian or a USian (or a Guatemalan) than I feel like an African, Middle Easter, East Asian, or South Asian.

I agree with you. I mostly see "Western" used as a synonym for "NATO". In addition to Mexico, there are countries in Europe (Russia) or democracies with huge economies (Japan, ROK, India, Brazil) that aren't described as Western.
I think of it as the corpus of cultures drawing heritage from the Ancient Greeks and Romans. If the Homeric epics have a home in your culture, it's Western.
That said, the term is muddied enough to be somewhat useless for general discussion. Particularly given how it's been co-opted by racist elements in American politics.
