Secondly, the Wikipedia article on the French Greens seems tendentious to me in that -- speaking of a party that has shared government and is therefore not without a history of some interest -- it consecrates no more than two sentences to the government period thus:

Dominique Voynet was to lead the party into government for the first time, joining Lionel Jospin's Socialist Party (PS) and the Communist Party (PCF). Voynet was rewarded with the cabinet position of Minister for the Environment and Regional Planning, before being replaced by Yves Cochet in 2001.

In general the party's history is sketchily covered. Yet "Skandrani's expulsion" takes up a full section and runs to about a quarter of the entire text about the party. All this for someone who is quite unknown to the public and never held any position, founder member or not. The same can be said of Pierre Brière, totally unknown Green expelled many years before Skandrani (1991). (I strongly suspect the Wikipedia article of having received the attention, quite precisely, of propagandists who want to blow up this affair out of all proportion).

Let me be clear. I am greatly angered and dismayed by Holocaust deniers and consider the French Greens quite right to exclude members who gave their support to any of these. But the two individuals in question are of no great importance. Making out the Greens have issues with anti-semitism is akin, as Jerome says, to making out France is an anti-semitic country, that Europe has not dealt with its anti-semitic past, etc : these are propaganda talking-points originating with the Zionist neocon right.
