No, you don’t have a point. You’re missing the point. The point is that America in English is not the same word as America in Spanish. They’re false friends.
False friends is the linguistics term for two words spelled the same in two languages, but with different meaning. For example, the word “glass” means ice cream in Swedish. We don’t tell the Swedish they’re using the word “glass” wrong, we accept that it has a different meaning in Swedish.
Sometimes the false friends are pretty subtle. The word “må” means “may” in Danish, but “must” in Norwegian. This can sometimes lead to misunderstandings, because unlike the ice cream example above, you don’t get any hints from context. You just have to know.
It’s the same deal with America. English-speaking countries (yes, the UK too), and all of the Nordics for that matter, use a continental model where North and South America are separate continents, and America is shorthand for United States of America. And the superior amount of Spanish speaking countries don’t give them the right to tell English speakers what words should mean in their native language.
