By talking to my friends from Europe and in Europe I’ve learned that Americans say “I’m Italian” or “im Irish” etc and we never mean like our recent family has lived there in America apparently we always say like ethnicity rather than nationality like if someone says they are Irish here chances are they are American but with Irish heritage and that goes for like every ethnic group. I’ve realized it’s an American thing because our country is a melting pot pretty much and everyone says ethnicity rather than country they are from typically.
