This is a dinvocation book, propaganda, ultimate egocentrism (Plenel loves loving humanity). We find the "Other" 3 times pages and permanent reference to evil superior and no other equal (2nd World War) of Western civilization in which he prohibited to claim any superior virtue into good.
He never descends into the arena of reality, no analysis, however short, on the compatibility of (or of) Islam (and its Sharia) with the Republic for example.
Few ideas, except that Muslims today would become the pre-war Jews, as it does not Sembete analysis, it goes alone. He recognizes his aversion to assimilation which would be a loss (I'm delighted that I do not exist), which must give way to Multiculti (regardless it works anywhere). What Sarkozi as Valls would be dangerous identity (hilarious! When we know accession without limit Sarko the racialist doctrine of miscegenation and profound lack of interest in Valls in France. The two friends have always supported an invasive immigration policy ). And that we must "think against itself" but NEVER against the "Other".
In a short moment of clarity he recognizes that the global oligarchy to mount any interest communities against each other ... totally omitting the fact that the said financial oligarchies, European, employers, media are unanimously in his camp, that 'they all call multiculturalism, unlimited immigration and using the same speech. And yes, to create conflicts communities, what better than to dissolve the national communities to import massively different foreign communities?
In short, the only advantage of this book is its brevity.
