Lol, like how you called him retarded, and instead of saying "Hong Kong is south of China (asia), whilst it's pointing towards Rio Dejenero in Brazil", you simplified it to "Returd it's pointing on South 'Mexico, U-S-A-U-S-A-U-S-A"
Well, if somebody is ignorant enough in geography to not be aware that the long pointy thing under Central America does not contain Hong Kong, a very well-known Asian city, then I would not want to refer to specific countries and cities within said continents.
