I believe this all started happening in France because a few decades ago the French (and Europeans in general) have such a low birthrate and steady-to-declining populations that they needed quick n' easy labor, and made it ridiculously easy for North Africans to flood into France for manual work. Marseille, on the southern coast, is even more Islamic than Paris.
This alone isn't such a big deal. But eventually, and not too surprisingly, happened:
Quote:"We were expecting Islam to adapt to France and it is France adapting to Islam," Robin said.
So now you have pockets of the city being illegally (but not enforced) closed down for prayer sessions, street level intimidation, neighborhood-level Sharia law, etc.
Here is your toxic mix:
1. An extremely generous welfare state
2. A fierce resistance to assimilation
3. Political correctness (French left-leaners whipping out
Le Card du Race if anyone offers any sort of criticism)
And there you have it.
Thus far, #2 hasn't really been an issue in the US. Immigrants, even illegals, tend to assimilate well into US society (yes, I know we can dig up some scattered examples of those who don't, but for the most part they do). And while the US government handouts are higher than they should be, they aren't anywhere near European levels... yet.
But it does serve as case study of what could happen in areas where these things exist.
