There's also the Republic of Ireland, the Republic of Korea, the Islamic Republic of Iran, the United Republic of Tanzania, the People's Republic of China, the State of Kuwait, the Kingdom of Belgium, the Republic of Latvia, the Principality of Monaco, the Kingdom of Spain, the Kingdom of Sweden, the Commonwealth of Australia, the Republic of Peru, the Republic of Paraguay, the Republic of Ecuador and a whole ton of other countries who are called by the last word in their official names because that is HOW ENGLISH WORKS.

And if you really gave a damn about all the people in Latin America, you'd call them by the proper names of their countries.

But if you insist I'm wrong, go over to lemmy.ca and post a thread telling them they're American. See what they think.
