Earlier quoted context omitted.
Yes I understand. Yet it in another sense remains geographically inaccurate or contradictory, and amusingly so. It's my personal opinion that when we see such a discongreguity that we should perhaps choose other words.
Words are never some sort of perfect encapsulation of their meaning. They only achieve that via their definitions. What you're suggesting is basically using the etymological fallacy as a basis for changing words. Because of linguistic drift, a majority of words would have up be changed at some point - words like "nice" which came to mean their opposite, for example.
Choice of words is an individalized thing and language allows us to be as flexible as we like within still getting the point across. If I choose to say "European" instead of "western" when contrasting with indigenous Americans that sounds fine to me. If you don't make that same choice that's fine too. We'll all be understood.
