btw, isn't this quiz meant to show up minorities? Just because of the Arabs in Egypt, thought they're the majority.
Of course, the fact that it is so obviously not is inconvenient to believers today. And, so, this metaphor/allegory meme was born and popularized.
Personally I do not buy that there are many ethnic Arabs in Egypt at all. Arabic-speaking people around the world did not start to identify themselves as Arabs until the rise of Arab Nationalism which began in the 1900s. This was a political movement that grew out of a combination of things including opposition to Ottoman (Turkish) rule over most Arabic-speaking people, Western Imperialism up to and immediately following World War I, and most importantly, the personal ambitions of the Sharif of Mecca and his opposition to Zionism, the growth of which encroached on his own political power interests, which by cynically and erroneously labeling as Arab and Muslim issues he successfully changed from a local issue into the cause-du-jour of the entire Arabic-speaking world and greater Muslim ulemma for the next century.
On the other hand, ethnicity is whatever identity people ascribe to themselves, so even if we can see that this trend is completely recent and more to do with politics than anything else, if Egyptians, Algerians, Sudanese and Iraqis want to call themselves Arab, then I suppose they're Arab. I just won't think of them as such. No need for a debate.
Hispania was the Roman province of modern-day Iberian peninsula, which includes Portugal. Therefore the Portuguese-speaking parts of Latin America are Hispanic.
I made a quiz based around important people in European History! If that interests you, please check it out on my profile. The name is "Influential Figures in European History".
If you come from a Spanish-speaking country, you are Hispanic.
Sure, there's a common language, and some of the "Hispanic" countries share some degree of ancestry.
But some of the biggest component of an ethnicity simply aren't there. There are so many ancestral cultures from which current Latin American come and there are so many cultural differences between "Hispanic" countries. Those created different national experiences and also affected the language, with many perceptible regional differences (not quite as the Portuguese divide, but still).
If you want to check further, here's a good starting point.
tl;dr: Saying that "everyone south of the border belongs to the Hispanic ethnicity" is like saying "everyone west of the Caucasus belongs to the European ethnicity", something no one would ever say.
Anyway, if that source is correct, then there are more in Canada than in Greenland, but Denmark + Greenland beats out Canada by just a hair.
But I'm not from US.
