There are lots of minorities in many countries. But these minorities were mostly based on etnic and/or religious groups. However being an Atheist, detaches you from the society based on your own thoughts or decisions. In a Muslim community, religion is very powerful in daily life. It seperates believers from non believers in a cunning sense. For instance; obtaining a proper position in a governmental/state organization, or even in private companies (because of their political status) depends on your religious expression.Another important part is the role of family. Since 99.9 percent of the population is Muslim, your parents are Muslim and most of them would kill themselves rather than watching you become a non believer. So they will teach you everything in a commanding and rewarding fashion.
This lifestyle leaves you only one choice; having two identities. First one is your formal identity, its like the way you talk or act in your job; and your hidden personal identity. You have to be really careful otherwise you will get discharged from your community. You cannot find a proper job, even your family will be really harsh on you.
We are in an ironic age, I can discuss Quantum Physics, determinism here and I cannot discuss even the basic principles of Islam in any kind of platform in my home, job or rest of my social life.
In Islam there were no reforms unlike Christianity so it is well preserved/protected. Muslim people are very proud to tell this. In fact, it is proves how corrupt it is. 1400 years of preservation gives you nothing but a Conservative mind.
