Wow you're one prejudiced, egocentric man, Kamui Zero.
BTW I'm from South America (Ecuador, to be specific). I can tell you that it's not about drugs at all, and generalizing it as such fills me with fear that there are others like you who would have such narrow-minded views of the world. This is further noticed in your "Foreign Music" topic, where you assume everyone you speak to must be from the USA.
This is an international forum. I suggest you exercise some tact and read a few books before writing your vapid statements based on your improper education on the world, and whatever drivel you've been spoonfed by movies/tv/media. Not everyone in South America is running a Drug Cartel.
Congratulations. The statements above are proof of how I deal with being prejudiced against.
Anyway...
In some countries in Europe these days, scientists have adopted the view that there are six continents. They have lumped Europe and Asia into "Eurasia", so we've got North America, South, America, Africa, Eurasia, Oceania, and Antartica. Some places erroneously say "Australia", which is slightly incorrect, as the continent and all the islands surrounding it are "Oceania" and "Australia" is just the island of Australia, and does not count New Zealand, etc.
In some other countries, they lump both America continents into one, which makes sense from a geographical standpoint; they are all one large mass of land, even with the separation being the Panama Canal. In some other countries, they do political separations, so Europe and the Middle East are separated, so you have Europe and "Asia" (even though the middle east isn't very asiatic), and they also have Central America, which is the countries between Mexico and Colombia, starting from Guatamala and Belize in the north, and ending with Panama in the south.
Regardless of how you slice it, a person living in North, South, or Central America could, by at least one definition, be an "American", regardless of whether they were born in the USA or not.
