Many times, it has been a “those are the ones I watched first because I was a kid when they were released, and now I defend them over everything” in my circles.

I love the idea and I try to send my message. I don’t know why it fell out of use.

Not as a nationality but as a continental identity (yes, just one). USians changed the number of official continental regions and their names, but you can trace the history of that and it is very recent. Many historical documents of real Americans (from America, the continent) talk about themselves as both their nationality (Cubans, Mexicans, etc.) and Americans. Just as a French is both a French and a European. That’s why that’s still the continental model of some countries. I think it makes sense to call USians a name that’s not stolen from other regions or peoples, even in English.
