Bernard Chazelle, guesting at Tony Karon's place, has some interesting data about France and the Jews:
Sarko’s Jewish roots are irrelevant. His strong support among Sephardic Jews reflect his tough stance against the antisemitic violence that flared up during the second Intifada. Many Sephardim live near or in the “hottest” banlieues and suffered the brunt of Muslim anti-Jewish hostility. Although this new form of European antisemitism has since declined, it would be tragic to dismiss it. To his credit, Sarkozy did not. Some perspective might be useful, however. Sharon’s attempts to portray France as an antisemitic country was silly pandering. The 2006 Pew Global Attitudes Survey asked the question: “Do you have a very or somewhat favorable opinion of Jews?” The answer was “yes” for 86% in France, 77% in the US, and 74% in Britain (the figure for that staunch Israeli ally, Turkey, was 15%). More interesting, among Muslim respondents, the answer was “yes” for 71% in France but only 32% in Britain (even though the UK has far fewer Arab Muslims). It would appear, therefore, that the antisemitic violence is hardly representative of French Muslim society as a whole.
Certainly not the impression one gets from the press coverage.
