Islam is often treated as an inextricable part of Arab culture, and in the minds of many in both the west and the Arab world, to be an Arab is to be a Muslim by default. While many religious minorities, notably the Druze, Jews and Christians, have found ways of reconciling their Arab identity with their beliefs, a far greater challenge faces the growing number of Arabs who identify as atheists, agnostics, or sceptics. Emboldened by the political upheavals of the Arab spring and facilitated by the growth of social media, these predominantly young men and women are becoming an increasingly vocal and assertive presence in Arab societies, despite facing the risk of imprisonment, ostracism, and death. Arabs Without God explores the roots and consequences of this phenomenon, as well as the experiences of those living as 'non-believers' in Muslim countries. Beginning with an examination of the history of atheism in the Arab world, it goes on to consider the circumstances which led these Arab Muslims to question their faith. It also examines the pressures they face in attempting to assert and defend their stance, both in Muslim countries and in the west, where they often find themselves caught between political Islamists who deride them as 'westernised' apostates, and a far right which regards all people from Muslim backgrounds as potential extremists. Arabs Without God argues passionately that these developments, previously ignored by western observers, are of vital importance to the future of Arab societies. For as the author says it is only 'when an atheist can be accepted and respected as a normal human being' that liberty will truly have arrived.
