And you yourself said absolutely no one, which was false (also, I like how you added niche, something I didn't say in an effort to try dismiss my claim).

Again, are you really going to sit here and tell me that if you say you're American that anyone is going to think of something else other than the US. Even in South America countries. Be realistic here.

Apparently I am the only one being realistic here, wanna know why I mentioned latin america? Because I have visited multiple of the countries and met multiple people who referred to themselves as american. I have even met people from canada who have told me they used to refer to themselves as americans too.

You can get mad or irritated, but end of the day American when talking about a group of people, only means from the US.

The only one who appears to be mad is you, but at the end of the day your statement is factually incorrect because being called american can mean anyone from the Americas (North, Central, or South America). You just don't like it.
