It is, in general conversation, entirely reasonable to say 'America' instead of the USA.

As is implicit in Rule I, no using sly tactics to undermine the Resolution. This is about general conversation between everyday people in an everyday environment (or online environment.)Argument I: It's a common tactic for shortening numerous names.The United States of America is not the only nation that does this. It's a very common tactic used by almost every nation in the world. While USA is indeed shorter, many people feel more comfortable using the term America instead. The USA is just as long as America (The USA - America), but quicker to type or write because it is one word. The complaints tend to only ever be directed towards the US, but here is a list of other nations that do this.- The United States of Mexico (although the name was changed in 2013.)- Federative Republic of Brazil- People's Republic of China- Republic of China (where the word Taiwan isn't even present)- Commonwealth of Australia- United Kingdom of Great Britain and Northern Ireland- Federal Republic of Germany- Republic of IndiaIn many of these cases, such as India and Mexico, the names (India, Mexico) are actually larger geopolitical areas. The land of Mexico, for example, includes all of Central America and Texas. The United States of Mexico only makes up slightly over half of all that, and yet we say Mexico instead. We say Britain despite how the nation doesn't actually own all of Britannia, or the UK despite how it leaves out North Ireland.It's common to substitute the countries name for a shorter or more convenient phrase, even if that phrase doesn't completely represent it. To say it is wrong of the US to do, one must also acknowledge that it is wrong for every other nation as well. It would then be unreasonable to say Taiwan or Brazil.Argument II: Words are only meant to convey ideas.Words, for the everyday person, isn't a part of technical language or jargon. Words have one purpose, and only one... To convey an idea. If they do this, they are as proper as normal people should require them to be. This is why when someone is improperly messing up a phrase or word to say something, we stop them and don't force them to say it right, because we understand the idea they are trying to convey.We simply speak, and if the other person listening understands the idea, we did it right. Rules and proper grammar are only guidelines to make speaking easier to understand, but as anyone to travels know, the guidelines change from group to group and yet everyone understands their peers. "Proper English" is simply understandable English. When saying America, everyone understands through context clues what you are talking about. Since everyone understands exactly what place you are referring to, it's as proper as it needs to be for conventional conversation.Shakespeare was famous for doing this. Even though he didn't use the "proper" terms, everyone understand what the image he tried to convey was.Argument III: The USA is the only nation with the word America in it.Since there is no other nation in North or South America with the word America in their name, it's entirely reasonable to say America. There is no other nation competing for the term. When saying "America," there is no other nation that you could get it confused with. The only problem arises if the other person is mentally deficient and can't tell when the conversation is referring to a continent or a country. The problem is then with them. If you then continue to say America, and they still don't understand, the problem is especially with them.Unless you can't convey the obvious idea of what you are referring to, a case in which every word or phrase is unreasonable and improper, the use of the word America is entirely appropriate.Argument VI: The United Kingdom is a perfect example.The UK is actually, in full, called the United Kingdom of Great Britain and Northern Ireland. It is entirely reasonable to call it the United Kingdom or to call it Britain. It is not reasonable to say Ireland as that name is occupied by another nation's title, a problem the US doesn't face with it's neighbors. It can be called the United Kingdom or Britain because both are major pieces to its name that adequately conveys the general idea. Likewise, The 'United Sates' or 'America' are both major pieces in the nation's name, and both adequately convey the idea.If there was another nation with the word 'America' in it's name, than it could be on the border of reasonable and unreasonable. If that other nation was, like Ireland, specifically known by that word, it would be completely unreasonable. Fortunately, the US doesn't face any of those issues.Even if the nation did, if the person you are speaking to understands exactly what nation or place you are referring to, it is still reasonable. As said in Argument II, all a word needs to do is convey an idea. If what you say conveys the idea as you need it conveyed, it is completely reasonable, even if it is not the "proper" term.Conclusion: It is entirely reasonable to use the term America since it conveys the intended idea (unless you simply screw up the idea, which is on you, not on the word.) And it is reasonable to use the word America as paraphrasing is common among almost all nations, and saying or typing America can be, to many people, more convenient.
