Obviously you've never been to Paris... let alone Marseille where Arabic is more widely spoken than French.
Oh my Dirk.You are wrong about many things but on my knowledge of France, you are miles out.
I have been going to France several times a year for nearly 40 years,on holiday,business and to visit friends and family.
I even lived there for a few years.
I know Paris and Marseille very well.And Lyon,Mulhouse,Toulon and many other towns and cities.
Marseille has always been very "African",part of it's attraction for me.
Toulon is a city few people visit, it is like a small Marseille but with the addition of The French Navy.
France has had a "Muslim Problem" for over 60 years(Partly their own fault) and it has got worse.
My gripe with your post was that you tried to compare The UK to France when there is no comparison.
1 in 8 French people are Muslim and in The UK it is 1 in 20.
