> Mayans and I are by now part of the greater western world
"Western" is used as short-hand for the cultures "that have some origin or association with Europe. The term also applies beyond Europe to countries and cultures whose histories are strongly connected to Europe by immigration, colonization, or influence."
Modern Mexican culture could be argued to be "Western". It would be difficult, on the other hand, to argue Maya culture is Western.
> I feel much more like a Canadian or a USian
Linguistically, the use of "USian" strikes back at your argument. There is no ambiguity when someone says "I am American," as people from only one country identify themselves as such. Using the term "USian" thus explicitly rejects one's affiliation with the United States.
