Cette illusion de la symétrie, c'est une illusion numérique Les groupuscules violents d'extrême droite sont aujourd'hui beaucoup plus nombreux à travers tout le territoire et ils augmentent en nombre chaque jour. Même en terme de victimes, macabre décompte, l'extrême gauche a fait une victime ces cinq dernières années, les militants d'extrême droite en ont fait onze, essentiellement des victimes ciblées sur des bases religieuses et raciales, des motifs profondément politiques. Depuis 1986, rappelle l'historien Nicolas Lebourg, 59 morts sont attribués à l'ultra-droite, contre six à l'ultra-gauche. C'est le retour des ligues. C'est un magma de groupuscules qui tissent un réseau de lieux, d'affinités, de thèmes.
Dominique de Villepin prend une position très claire (mais très verbeuse)
Le mythe de la symétrie "extrême-gauche - extrême droite" est une illusion qui sert l'extrême droite.
Quand la gauche est violente elle nuit à la gauche, quand la droite est violente elle sert la droite.
