He works with Le Monde newspaper and Causes Communes, a journal specialized in migrations edited by Cimade. In 2013, he published “Poussière d’âmes” in which he questions the collective and individual memory during the Ukrainian and Rwanda genocides. His last book, “En finir avec les idées fausses propagées par l’extrême droite” (Putting an end to the misconceptions propagated by right extremists) refutes, one by one, over 70 preconceived notions about extremist thought. Beyond the facts, he unveils a propaganda-like discourse according to which human equality is not a blessing but a menace.
