Cultural Muslims are religiously unobservant, secular or irreligious individuals who still identify with the Muslim culture due to family background, personal experiences, or the social and cultural environment in which they grew up.

The term is a political neologism paralleling the term "cultural Christian".

Malise Ruthven (2000) discussed the terms "cultural Muslim" and "nominal Muslim" as follows:

There is, however, a secondary meaning to Muslim which may shade into the first. A Muslim is one born to a Muslim father who takes on his or her parents' confessional identity without necessarily subscribing to the beliefs and practices associated with the faith, just as a Jew may describe him- or herself as Jewish without observing the Halacha. In non-Muslim societies, such Muslims may subscribe to, and be vested with, secular identities. The Muslims of Bosnia, descendants of Slavs who converted to Islam under Ottoman rule, are not always noted for attendance at prayer, abstention from alcohol, seclusion of women and other social practices associated with believing Muslims in other parts of the world. They were officially designated as Muslims by nationality to distinguish them from Orthodox Serbs and Catholic Croats under the former Yugoslav communist regime. The label Muslim indicates their ethnicity and group allegiance, but not necessarily their religious beliefs. In this limited context (which may apply to other Muslim minorities in Europe and Asia), there may be no contradiction between being Muslim and being atheist or agnostic, just as there are Jewish atheists and Jewish agnostics... It should be noted, however, that this secular definition of Muslim (sometimes the terms cultural Muslim or nominal Muslim are used) is very far from being uncontested.

David Ernest Duke (born July 1, 1950) is a former Grand Wizard of the Knights of the Ku Klux Klan an American activist and writer, and former Republican Louisiana State Representative. He was a candidate in the Democratic presidential primaries in 1988 and the Republican presidential primaries in 1992. Duke has unsuccessfully run for the Louisiana State Senate, U.S. Senate, U.S. House of Representatives, and Governor of Louisiana.

A former Grand Wizard of the Knights of the Ku Klux Klan, Duke describes himself as a racial realist, asserting that "all people have a basic human right to preserve their own heritage." He is in strong opposition to what he asserts to be Jewish control of the Federal Reserve Bank, the federal government and the media. Duke supports stopping both legal and illegal Non-European immigration, preservation of what he labels Western culture and traditionalist Christian "family values", strict Constitutionalism, abolition of the Internal Revenue Service, voluntary racial segregation, ardent anti-communism and white separatism.

Suhaib Webb is a contemporary American-Muslim educator, activist, and lecturer. He is currently the imam of the Islamic Society of Boston Cultural Center (ISBCC), the largest mosque in the New England area.

He was born William Webb in 1972 in Oklahoma to a Christian family, including a grandfather who served as a preacher. At age 14, he lost interest in religion going through a self-described spiritual crisis. He also began engaging in delinquency by joining a local gang, was involved in a drive by shooting, and became a successful local Hip-Hop DJ and producer, making records with various artists.

After converting to Islam in 1992, Webb left his career as a DJ and studied at the University of Central Oklahoma, where he graduated with a Bachelor's degree in Education. He also studied privately under a Senegalese Sheikh, learning enough Islam and Arabic to become a community leader in Oklahoma City, where he was hired as Imam at The Islamic Society of Greater Oklahoma City. He simultaneously started teaching at Mercy School, an Islamic K-12 school in Oklahoma City.
