Racism
Classicism
Hypocrisy
It's all built in the French system of bureaucracy and government.
EG: If someone does NOT have a "
Livret de Famille" that clearly shows the marital status of their grandparents then they WILL be excluded and prevented from participating in segments of French society. And they'll smile nicely and be down right annoyingly polite as they close the door in your face.
As I always say...
Try renting an apartment
(if they'll take your money) and then spending a year in France. Trust me that anyone who does that will also be praying that something comes along and kicks the French out of France.
