The situation in France has always been historically different. Partly because of the principle of 'Laïcité/secularity' which followed the Revolution, partly because of the very recent (to me) war of Algeria. Both have resulted in North African Muslims in France, even now 2nd, 3rd or evern 4th generation Muslims- even those who do not wear any traditional clothes, etc- encountering daily discrimination, insults, rejection, of every kind- day in, day out, and massive unemployment.
Building huge resentment and making some young people, especially young men- very easy to target by extremist groups.
Does anyone remember the film 'La Haine'?
Charlie Hebdo poured petrol over the flames, and are doing it again- and a large part of the Islamophobic population is helping carry the can- and doing it again. A very dangerous situation.
There is a massive difference between 'appeasement' and deliberate fanning of the flames. And I am not in any way shape or form, excusing those heinous crimes committed by a few mad men. They carry in their pockets a copy of a postcard sent by French soldiers during the Algerian war- of Arad heads severed and lined up on a stone wall- to encourage them. The Algerian war was recent enough for their fathers to have been involved.
The situation in France is unique totally different to the UK.
