> Imagine calling Canadians and Mexicans “American” because of the continent.

I've seen "North American" used like that pretty often, actually.

> If you’re annoyed by being lumped under “Westerner” you might be able to relate.

I'm not. Should I be? It makes sense.

I agree that "Asian" doesn't make sense in the way the West tends to use it. "East Asian" is somewhat better, though still not 100% geographically accurate. But then "Westerner" isn't really accurate either; it's just the best commonly-accepted term for a useful concept.
