So, it's an insult, but only to those whom you are not calling the name? Interesting.

While it is true that people from Europe can be called European, wouldn't someone from North American be called North American? If they were from Estados Unidos Mexicanos, as geonuc mentioned, why would referring to them as Mexican be any different than referring the people from the United States of America as American? It's a historical accident, kinda like dwarf planets not being planets, since the union was more or less first.

We are all Americans. Let me give you all a big hug. Even you guys in France.
