The largest number is that of people from Africa : the Maghreb- (so Arabs) , and countries in black Africa that used to be French colonies. There also are coloured people from Martinique and the French territories overseas DOMs and TOMs; a substantial number of people from Asia (Vietnamese, Chinese, Cambodian, etc...). Of course there are tourists and business people from all over the world who are not necessarily white and are in Paris for a short term.
France is an ethnically diverse nation, with about 2.5 – 5 million "black" people.
Unfortunately yes there are many foreigners invading the once great city known as paris. The worst of these people are muslins and northern Africans, or as the media calls them :"youths". Don't go to paris, it has gone way downhill since muslims took over.
It's very sad, really, how the French not only allowed and encouraged this to happen, but defend their demise and call me racist(even though islam is not a race) for defending what once made paris a good city.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
