We live in France, been here 14 years and have become attached to the country and its people.
There's been a very big problem for many years with immigrants from N. African countries, which were french colonies. Just look up the France - Algerian war.
Between 1 in 7 and 1 in 10 of the population are Muslim, who are mostly observant and don't integrate. Even in our tiny departmental capital, pop 22,000, there's a Muslim ghetto. The mosque was set on fire a few months ago.
