A book written by the late editor of French satirical weekly Charlie Hebdo, has been published posthumously. The book, which upholds the right to ridicule religion, was finished two days before Stephane Charbonnier – known as Charb was murdered along with 10 colleagues by Islamic terrorists in Paris in January. The book’s publishers say the tome argues that the fight against racism is being replaced by a misguided struggle against “Islamophobia”. Charb had received numerous death threats following Charlie Hebdo’s publication of cartoons featuring the Prophet Muhammad in 2006. The magazine’s offices were firebombed in 2012. The book, entitled “An Open Letter to the Fraudsters of Islamophobia who Play into Racists’ Hands”, went on sale in France Thursday.
