The Maldives.

As every Maldivian citizen has to be Muslim, all deviant religious convictions are strictly forbidden. The government does not distinguish between national and expat believers. The tiny number of indigenous believers is not able to meet publicly, let alone worship together. On the contrary, they have to practice their faith in utmost secrecy, always in fear of being discovered. While the authorities closely monitor all religious activities that they perceive to be suspicious, social control also remains extremely high. Maldivian citizens agree with the heavy handed authorities because they see freedom of religion as freedom to discuss religious issues related to Islam. This freedom was non-existent under the former regime governing the country. Maldivian society demonstrates this attitude towards all kinds of beliefs or convictions, be it Christianity or Atheism. Additionally, the government has increased control of all media. (Open Doors.)
