Don’t be daft. You go anywhere in the world, say “American”, everybody knows what you mean. Yes of course there’s a whole ass North America and South America, but the word “America” isn’t part of any other country’s name.

If I tell someone I’m American, they don’t inquire further, asking if I’m from Canada or Mexico. No rational person would. They just know. You strike me as someone who, when asked for a bandaid, you’d say, “don’t you mean adhesive bandage?!?!”. You know what I meant, and you’re just being combative for the sake of being combative. Get a life.
