I am a newly-converted atheist. I was raised muslim by muslim parents in the world largest muslim country (Indonesia). The God Delusion really has a great impact on how I view the world and 'the existance' of mythical creature so called god.
Atheism is indeed not a wise choice for a person who comes from the country like Indonesia . In fact, if I choose to disclose my views on religion to my fellow Indonesians (especially my family), I'll risk many things, including to some extent my own life. But, I've never felt such a relieved feeling like this, being an apostate and becoming an atheist. My atheist friend once said to me “losing an illusion makes me happier than finding the truth”.
