I never said laws like these were the only source of integration problems. Clearly there are other factors at play. But laws like these do not help at all. Also what are you refering to with marginalization in egypt, lybia, algeria. All of those countries are muslim majority countries.
I tried to explain that this extremism growing in the muslim world (and not only in France) has nothing to do with marginalization , since it's growing even quicker in muslim countries.
