<quote><p>So immigrants tend to embrace their new culture. Most people who fled Soviet Bloc countries turned into ardent haters of communism - why wouldn't people who fled Muslim theocracies turn out to be pretty ardent haters of Muslim theocracies? They may keep the religion, but in a more moderate, modern form instead of the controlling throwback currently dominant in the Arab region.</p><p>And those are first-generation immigrants. What about their children? They'll raise them Muslim, of course, but they'll raise them *French*. They'll be well-educated and (knowing children) liberal. They'll hear the stories about how bad the home country was, and unless their new country does something to disillusion them (like your racist shitspouting) they'll be patriotic for *that* country, not some country they've never been to and hear only bad things about.</p></quote>
Immigrants embrace the new culture when they have to, which isn't the case anymore, since they're more than enough to build their own communities. You can live in France without speaking french, without eating french food, without dressing like french people, without knowing french history or any part of french culture, and then wonder why you can't blend with french people. Muslims are also actively pushing for their religion into the public life, in a country where religion is becoming more and more a private thing. And for their children it's even worse, they won't have any chance to try to integrate because their parents already put them outside french society, and if their parents can't teach them proper french, they'll struggle in school, pushing them further away. And you end up with african flags used instead of french flags when celebrating, among other things, which isn't really patriotic (well it is, but not for France).
Without calling them a fifth column, you'd have to be deluded to believe the muslims are well integrated in France. It's not their fault though, problem lies with the immigration policy which allowed too many people in without caring about their insertion into french society which is very different from the one they came from.
