They should be called United Statesians in English. I know États-Uniens is the official name in French.
What is it in other langages? How can we promote such use?
Why am I asking? The US administration is currently a disgrace on the world stage, and I am thinking how it unjustly hurts people from the rest of the American continent.
I used to work with a Canadian (From Vancouver, iirc) who used to emphasize “North American” when people made the wrong assumption. I guess it makes sense once the focus is on region/continent instead of country.
