José Manuel Ríos Valiente/Flickr How do you spot a radical jihadist? According to the French government, several signs should alert people that “a process of radicalization is underway.” “They” (meaning radicalized individuals): mistrust old friends, whom they now consider ‘impure’… abruptly change their eating habits … no longer watch television or go to the movies because [these may show] images that are forbidden to them … change their attire, especially women, with clothes that conceal the body … [and] stop listening to music because it distracts them from their ‘mission.’ French governmentThese individuals, the French government states in new anti-jihadist literature published Wednesday, also “withdraw into themselves, displaying antisocial behavior, rejecting every form of authority, or life in community.” Not unlike a Symptom Checker post on WebMD, the guidance contains a caveat: “The identification of one or more of these signs does not necessarily indicate radicalization.” So how exactly is someone in France supposed to tell the difference between ‘us’ and ‘them’?
