Can Europeans tell the difference between Arabs and Southern Europeans?

The answer of 451 is very official but it does not answer the question. It is difficult to distinguish between North Africans and Southern Europeans. For example, some cities in France are mostly Algerians, and Algeria was once a French colony. And other factors, Morocco was occupied by Spain, Algeria was also occupied by Morocco, Tunisia is also difficult to distinguish, Egypt is easier to distinguish

Some people can still tell the difference by color, and some people in North Africa still have to distinguish Darker, the genetic factor is still there, some people can't tell it, but their French and Spanish are not orthodox French and Spanish, just like British English and American English. In addition, you can also see the way North Africans greet each other, it will be mixed Arabic

Another obvious thing is that these Arabic-speaking countries in North Africa are Muslim countries, they are all Muslims, and Europeans haha. . .
