What civilization? Secular, socialist Europe, that doesn't care enough about its own survival to replace its native population through reproduction?
The statement quoted sounds like "Appropriate remark!" boilerplate, rather than anything composed to make a real point, but it wouldn't surprise me if Pope Benedict thinks there's a greater chance of mass conversions of Moslems than there is of a rebirth of Christianity among culture-of-death ethnic Europeans.
Secular, Socialist Europe is the trustifarian brat living off the social and political capital of Christian Europe. However, there are still many who either remember their heritage, or understand taht secular liberalism is like AIDS to their cultural and political defenses against invasion.
Intersting point and it may prove valid. It couldn't hurt.
I guess I have a different interpretation from everyone else.
By all means, take the riots as a sign that there are dissatisfied unassimilated people in the country. But the only fundamental way to deal with that is to stand up for French (presumably Christian) society, explain what is good about it, and integrate the immigrants into that. Instead of just hoping that if they ignore the problem, or convert France to Islam, it will somehow placate them.
It sounds pretty conservative to me. Of course it has a thick sugar coating of diplomacy on it.
