France chose to colonize Muslim areas of Africa.
Then it admitted those Muslim Africans into France to provide cheap labor.
Those Muslim Africans are far more fertile than the native French. Muslim African families have 2.6 children per household. The native french have 1.6 children per household.
Those children grow up, make money, go to school and many choose to preserve and promote their culture over the native French.
The native French were naive and too arrogant to understand the changes they were making to their own culture.

Yep. And after independence many of those people were given the right to immigrate to France itself, if they so desired. Same thing with the British.
You reap what you sow.
We aren't much different with our own massive immigration issue.
