Tora, you´re a genious.
Dixie, even for us, the latinamerican guys, is too large to call them "estadunidenses", I prefer the called them as we do in my country "Gringos", even if they are from Chine, Costa Rica, Norway, etc.
When my foreing friends, from Russia as an example, call them "americans" I don´t have any problem. I only explain to them the geographical division. But I neve go into this problem of "names".
People from Costa Rica, Perú, México, Cuba etc, who live at USA, are called here in my country "Pochos".But let me explain that we called in this way only people who has the USA nationality, but their origin (parents) is from any country of Latinamerica.
The rest of latinamericans who live in USA we called inmigrants, or ilegals, or "mojados".
We felt a big respect for the people who has to left their country to go to another place to look for a better life, even if we prefer stay here into our poor country.
It doesn´t matter how the people call you, every one have an escense, the latinamerican escense, the caribbean escense,etc. And all make the countries, the world, the life.
It Wouldn´t be frontiers.
