It might (not) surprise you to learn that what I call Cyprus is called "Zypern" by Germans and there are a lot more copper related names for the place.
Closer to my home, what I call London is Londres in France and London in German. The city in question was named by a bunch of what would become Italians (Romans) - Londinium was named by a murderous bunch of colonial invaders.
I have insinuated an awful lot from your comment and "replied" to those insinuations as best I can.
I am somebody and I use the term America routinely to describe the USA and the term Americas for the entire continent. North America is US + CA and Southern America is Brazil, Argentina, Peru, Paraguay, Chile, Uruguay and ... oh there are rather a lot more. There is also Central America which is the countries that join the north to the south.
I get that you have an axe to grind about which America is which and who owns which name. I have some sympathy for Brazil getting pissed off about Amazon (the company) too.
I try to understand all points of view - its quite interesting.
