Now, I get the logic you're operating on; just like people who are generally 'from Europe' can be referred to as 'Europeans', that's only because there is no *country* with 'Europe' in its name. If there were, you'd only refer to people *from that country* as 'Europeans'. In the case of 'Americans', there *is* a country with 'America' in its name, so we don't refer to everybody 'from the Americas' as 'Americans'. See the distinction? No, I doubt you do.
