Brazil was "United States of Brazil" a long time ago and, never, we called ourselves "United Statians". So, who uses it today, is a political agitator or a truly ignorant. Your argument is a lie, and clearly you are here by political interests. And if it was that important call them "not American" to do a distinghish, all the press, ABL (Brazilian Association of writing) and others have call them like that a long time ago, as well.
