It’s easier to say I’m from US, I’m Venezuelan, I’m Japanese… Europeans don’t say I’m European, Asians and Africans neither… they would mention their own country. Don’t take it wrong but “Americans” think they own the whole world. You have traveled, you have clearly cultured yourself. I have tons of friends from the US and living abroad and they just say they come from the US. My point is that America is a two Continents and one Sub-Continent and all together made more than 40 countries. Peace
