The ‘America’ in United States of America refers to the continent. Today, in English, ‘America’ by itself almost always refers to the USA. These are facts.

Names can refer to more than one thing. That which names refer to can change over time. This doesn’t break any rules of naming. These are facts.

If people started calling Jesus ‘Nazareth’, then ‘Nazareth’ would refer to Jesus.

This is what happened with ‘America’. It doesn’t matter that you don’t like it. Your dislike obviously didn’t prevent it from happening. Do you know why? Because your preferences don’t determine how people use names.

It would refer to Jesus in addition to referring to the city.

So you must also believe that RuPaul is really a woman.

Exactly, because Jesus comes from the city but he's got a real name :Jesus. Unlike the U.S. who is using the name America as their name now when it is the place where it came from just as Jesus was called from Nazareth. You yourself understand this very well right? This is what I have been telling you. U.S. adding the name "America" meant that the nation came from America and that is not the name of the nation but a continent. If you put the two examples together, Jesus = U.S., Jesus of Nazareth, U.S. of America, both have a biographical place where they came from and not that it is their name or if not Jesus would had changed his name to "Nazareth" and so the U.S. using the name of "America" would had correlated to that but you know this didn't happen because it is wrong.

Very good, although it is actually "United Mexican States", not United States of Mexico :)

So shameless

How is it shameless?

I ask you because you keep saying that America has different meanings. You yourself wrote that America means the name of the continent. Then you say that the USA can be named America. I ask you then if the USA can be named America and the meaning of America is originally a continent how can a nation/country be called the same name as the continent in which that nation was founded on? The only way that what you say could be understandable is that people have been wrongly using the name America to call a country which its name is United States and is in America. So the supposed meaning you talk about is just people calling the U.S. "America" because somewhere someone started to call it that way but it really means the continent.

I don’t deny that ‘America’ originally referred to South America. What I mean by “multiple meanings” is that the name is used to refer to various things. It has multiple referents.

You agree with me and the truth by stating that the name refers to various things. The bulk of our disagreement is based on your misunderstanding, or your pretended misunderstanding, of what I mean by “multiple meanings”. ‘America’, in a very basic sense, means ‘the land of Amerigo’ or some version of that. I have never denied this, or that ‘America’ first referred to South America, or that many people use the name to refer to all of the Americas.

Most of my posts counter the false claim that it’s “incorrect” to call the USA ‘America’. When I say that ‘America’ can “mean” the USA, I am not saying that its original meaning was ‘USA’ and not ‘the land of Amerigo’. That’s absurd. I am using the word ‘mean’ in a very common and standard way. You misunderstand me, either intentionally or unintentionally.

Sure, America was written on a map where South America is today, but you keep staying on that without going further into how the entire continent was later named America. Is there a reason why you keep avoiding how the name was coined and how it was explained in the Universalis Cosmographia by Martin Waldseemuller and Mattias Ringmann. Everything in the new world was that continent, and when all was mapped and discovered became the fourth part of the world, a new continent, America. The U.S. took the name of the continent and it seems that it wants to keep it and change the continent's name to The Americas.

Or simply use "America" for most part of the continent, and Anglo America for the very North section, mainly including Canada and the United States.

Guyana speaks English and isn't in the Northern part.

Have to? No. North America and South America work perfectly and are very well-established.

There aren’t any rules that dictate which names we “have to” use. That’s why the whole world doesn’t have to call the Americas ‘America’. We don’t have to call North America ‘Parias’ just because that’s what appeared on the 1507 Waldseemüller map. The whole world doesn’t have to use the names that some Latin Americans prefer.

The whole world has to use the names that United Statians prefer, of course manipulating the media. Check how they use Wikipedia to call the US like the continent.

China had to come to start giving them lessons.

Everyone can use whatever name they want. If they choose to use a name that isn’t common in the language they are speaking, then they are responsible for any confusion.

English-language Wikipedia and English-language media often refer to the USA as ‘America’ because that is what it’s often called in English. There’s no manipulation. They’re just using English properly and in a way that English speakers easily understand.
