USAian.
Sounds cooler too because https://dragonball.fandom.com/wiki/Saiyan
USian has a self-evident meaning: a person of the US. it’s certainly more clear than “American”: a phrase which i struggled with for years as a child because i learned about continents and geography before i learned about countries and genealogy, and hence had to un-learn some of the associations i made with the word early on (despite having been born/raised in the US!)
USian lacks a strong connotation for the vast majority of speakers at present. i’d like a chance to explore it as an alternative label at least for describing myself. as demonstrated by neighbor comment about “yankee” or “ham radio”, it’s the recipient who grants power to a slur — not the speaker. so if you’re a USian like me then get over yourself: don’t deny yourself (or me) the opportunity for a better label.
That's not going to make anyone happy. It's Türkiye.
Some people you just can't insult.
It's impossible to insult someone who refuses to be insulted.
But from your clarification it seem you simply meant American without any further qualifications.
