The Law of March 15, 2004, which prohibits the wearing of conspicuous religious symbols in public schools, marks a philosophical and legal turning point, with the advent of a neo-secularism that challenges the equality of religions by targeting Muslims, in particular, and freedom by extending the duty of neutrality to citizens. Prohibitionists were active but in the minority in the 1990s. This reversal stems from repeated campaigns to demonize women wearing headscarves, targeting their presence in all spheres of social life: work, leisure, university, public space, and media. Their construction as a “problem” relies on the permanent association between religious signs and “Islamism” to sometimes make the link with terrorism.
