Finkielkraut is not racist, he sees the exact situation of the Jews in France, where synagogues and jewish schools have to be protected by police in a more tighter way than banks to prevent arson and attacks. The radical left in France is completely supporting the islamist groups. It sees them as representing the new "proletariat", since workers no more vote for marxist parties. You can see people like José Bové, Olivier Besancenot, Marie-France Buffé (both three radical candidates to presidency) attending meetings with islamic organisations. They are completely against Israel in any circumstance.
