Well, as a South American I don't want to be confused with "Yankees" (in the absence of a better term), but I have no problem with the adjective American to refer to someone citizen of the USA. The way I see things, the idea of America as a new continent was so strong and powerful that different nations took it to mean different things, and nobody had the exclusivity over the word. So, it just happens that there's a continent named America and also a country named America, but one thing is one thing and the other thing is the other thing.Actually I think most South Americans (and Canadians) prefer to be identified in a way that separates them from the USAians. And since the USA seems to have claimed American, they don't want to be confused for people who might have voted for Trump.
So, we have
The United States of America
Estados Unidos Mexicanos
(See? There isn't just one United States after all. And until 1950 something we used to be...)
Estados Unidos do Brasil
(And now we are...)
República Federativa do Brasil
(Yeah, same thing as Germany)
So, technically, if somebody says they are from the United States, you'd be right to ask "Which one?" And then you'd have to say I come from "The Federative Republic."
AS for not mistaking us Brazilians with someone else, yes we are Latinos, but then we consider "Latinos" people from most Latin America, parts of Canada, Portugal, Spain, France, Italy and Romania. We can also be considered culturally Iberians.
But please, please, do NOT call us Hispanics! No Brazilian likes that.
And finally as far as my English speaking side is concerned, I identify mostly with California, because that's where I spent most of my time in the USA, and where I studied part of my high-school years.
As for the Trump reference, I'd rather not get into details about another country's president, but I found our press coverage to be so shamelessly biased, simply repeating what some foreign press organizations were selling, that I actually began to see him under a more favorable light. And what matters to me is the situation around here. And if you look at countries like Cuba, Ecuador, Bolivia and Venezuela (especially), you might understand why I don't want this brand of socialism anywhere near us. Add that to the fact Workers' Party ex-president Lula has been indicted of several crimes, (and I hope he spends a long, long time in jail), you won't have problems to figure out where I stand politically.
