Idk, seems like if you're already established somewhere and someone else comes in and tells you the place you live and your ancestors have lived in for millennia is now called "America"... Dunno, that feels kind of wrong.
Second, that's the word we use in English. If you've lived here for millenia, you can use the appropriate word in your own language.

All English-speaking countries count them as two continents though.
And in English, it's conventionally "the Americas" even if you believe it's a single continent.
Kind of like, we call it the Bahamas, not Bahama, even though it's one country. It's linguistic, not conceptual.
Germans don’t call the place they live Germany. They don’t even call themselves Germans. But I call it Germany because that’s the English name for that place.
Oh nooo, I'm so offended that Chinese people have a name that I didn't agree too for the place my ancestors are from for the last 350 years. Someone give me some pearls to clutch.
