For Non-Muslims
Religion plays an important role in Algerian society, making it relatively homogeneous. For the average Algerian, being Algerian means being Muslim. However, this is not always so.
People without religious affiliation tend to be particularly numerous in Kabylie (a Kabyle-speaking area) where they are generally tolerated and sometimes supported; notably, Matoub Lounes is widely seen as a hero among Kabyles, despite (or because of) his lack of religion. In most other areas of the country, the non-religious tend to be more discreet.
The study of Islam is a requirement in the public and private schools for every Algerian child, irrespective of his/her religion.
Muslim women cannot marry non-Muslim men (Algerian Family Code I.II.31), and apostates are disinherited (Family Code III.I.138). A marriage is legally nullified by the apostasy of the husband (presumably from Islam, although this is not specified; Family Code I.III.33).
The majority of cases of harassment and security threats against non-Muslims come from the now nearly destroyed Armed Islamic Group, an organization fighting the government who are determined to rid the country of those who do not share their extremist interpretation of Islam. However, a majority of the population subscribes to Islamic precepts of tolerance in religious beliefs. Moderate Islamist religious and political leaders have criticized publicly acts of violence committed in the name of Islam.
Missionary groups are permitted to conduct humanitarian activities without government interference as long as they are discreet and do not proselytize openly. If they do, they are sometimes arrested and sometimes left alone. Many of the "home churches" in which Christians worship are in contact with the Government, and none report being intimidated or threatened.
Eating in public during Ramadan (particularly for people who "look Muslim") is legal but attracts public hostility in most areas, except for some areas of Kabylie; most restaurants close during Ramadan.
"Offending the Prophet," however, is still a criminal charge. If indicted, the defendant faces up to five years' imprisonment and a heavy fine (Abdelkarim Siaghi case - May 2011).
In general noncitizens who practice faiths other than Islam enjoy a high level of tolerance within society; however, citizens who renounce Islam generally are ostracized by their families and shunned by their neighbors. The Government generally does not become involved in such disputes. Converts also expose themselves to the risk of attack by radical extremists.
