In this magazine, there's a major section devoted to antisemitism.
What we find out (to summarize) is that Antisemitism in France isn't more vivacious there than elesewhere. But it does astonish coming from the country of emancipation and the human rights. Five big sources have fed it throughout history:
The religious antijudaïsm, catholic in origin.
The socialists' and traditionalists' (devoted to rural society) anticapitalism.
The antirepublicanism linked to hostility towards free-masonry.
Racism with scientific claim
After WW2, especially after 1967, condemnation of zionism as a form of colonialism and imperialism.

The French Republic resisted those different antisemitst assaults with Dreyfus rehabilitation in 1906 being the prime example. Only war and defeat allowed for its legal regression. A complex history results from it, with integration and exclusion phases. It would be better to say a long integration phase shredded by exclusion moments. Today, the jewish question is less the antisemitsm one than the communityism one. (Corsicans, gays, muslims (with the veil) and all kinds of minority (sexual, religious, regional, cultural) groups want a form of recognition and all this hurts integration efforts.
I find quite interesting that it's secularism that made jewish integration possible as freedom of religion was what resulted from it (as religion became independant from the temporal power in 1791) but it's the present policies of the jewish state of Israel which is blamed for the current wave of antisemitism. As if a non religious believer were not allowed to criticize the religious oriented policies of another state. Or using the same word "antisemitism" for those who committed crimes against humanity (more precisely the holocaust) as for those who don't agree (using only words and no violence) with Sharon's policies..is that a good idea?
