I think many people take the United States, or the idea of being from the United States, way too seriously. I think people in the United States (and the US government in particular) are particularly bad about this.
I also find it annoying that’s it’s difficult to concisely and non-awkwardly describe the United States by name. "America" is right out; America is just tad larger (nearly too continents in fact) than the US. "The states" is too vague and "the United States" or "the United States of America" is just too long (not to mention that other countries, like Mexico, are also "the United States"). "The USA" is hard to say and it pronounced differently in most Latin languages than in English.
USA is a perfectly pronounceable acronym and I think it’s crazy that we insist on reading the letters out. I think everyone should start pronouncing "USA" and calling the country "oosah" (with the u as in in food or Ubuntu). It’s citizens would be Usaites or Usians or something similar.
I think this would give the world a concise and unambiguous name for the United States and at the same time make it harder for people to take the country seriously.
