you can just say ~~Americans~~ people, everyone will know ~~who~~ you're talking about USA.

Fixed this for you. Kind of a pet peeve of mine when people use 'defaults', like everyone on the internet are in America, or if you're talking to someone from a capital of a different country they will assume you're also in the capital, everyone lives in America timezone, everyone using English uses en_US locale, and if by some bizarre chance you're in another country you can only switch language and country together, etc
