Don't West Africans usually speak French or some other colonial language? I think most French speaking countries are former French colonies in Africa. Also the black countries in the Caribbean like Haiti speak French. So even in their own countries they speak a white man's language today.
North African countries also have some French but the Arabs there still speak Arabic. All the Jews there learned French and fled to France, Quebec, or Israel when North Africa got independent. Jews were French citizens in North Africa.
