What really got me about this story is this part:
O Globo called the joke "full of prejudice" as U.S. athletes arrive to compete in the games, which begin next week.
Now who's full of prejudice?
Rio Mayor Cesar Maia told CBN Radio that Brazilians are understandably sensitive about being compared to much less developed countries — especially by Americans, who are often seen here as arrogant in their views on other nations. (emphasis added by me, but hardly necessary)
