You are being downvoted, as should you, but I still want to answer your questions.

> Not sure what language you speak natively

Polish

>but no one corrects Italians for saying "Germania" instead of Deutschland, nor Spaniards for saying "Nueva York", nor the French for saying "Angleterre".

It's literally the second thing people learn when learning a second language. The first is how to say your name, the second is where are you from. And then you pretend to be from somewhere else and do to the above. After the first lesson of any language the only thing you know is your name and names of other countries lol so I'm not sure what are you talking about
