In this new essay, psychologist Rachida Azdouz takes a real x-ray of the anti-racist discourse, to illustrate the divergences, even the fracture, between its supporters. Mastering the art of making points of view dialogue and of qualifying lived experiences, she dissects the concepts, highlights their relevance and their perverse effects. She goes back to the sources in order to explain, without justifying them, the excesses of radical militancy.
