Since the October 7 massacres committed by Palestinian groups in Israel, a propaganda war broke out on social networks and in the « mainstream media » between two competing campisms : “Zionist” campism, which denies (or considerably relativizes) the massacres of Palestinian civilians committed by the Israeli army ; and “anti-Zionist” campism [1], which denies (or at least strongly relativizes) the massacres of Israeli civilians perpetrated by Hamas, Islamic Jihad and other groups or individuals on October 7, 2023.
