Similarly in Spanish OP, we say estadounidense as the demonym for something from USA. We often use americano interchangeably though, but that gives room for confusion sometimes.

I think you should have posted this in Unpopular Opinions hah. I don’t give much weight to it and, as long as everyone knows what you mean by American when you say it is fine, so I don’t necessarily agree with your opinion that it hurts the rest of the continent. But as far as semantics go we both know the question is about as old as the country itself.

We’re gonna get downvoted to hell. See you there :)
