Religious trends in the United States Although the United States is still home to the largest number of Christians worldwide, the nation has started to reflect a more diverse religious landscape in recent years. Americans now report a wide range of religious beliefs and backgrounds, in addition to an increasing number of people who are choosing to identify with no religion at all. Studies suggest that many Americans have left their previous religion to instead identify as atheist, agnostic, or nothing in particular, with many reasoning that they stopped believing in the religion's teachings, that they didn't approve of negative teachings or treatment of LGBTQ+ people, or that their family was never that religious growing up. Christian controversies Over the last few years, controversies linked to Christian denominations have plagued the nation, including reports of child sexual abuse by the Catholic Church, the Church of Jesus Christ of Latter-day Saints, and the Southern Baptist Convention. Christian churches have also been accused of supporting discriminatory actions against LGBTQ+ people and people belonging to other religious groups. In addition, there have been increasing concerns about Christian nationalism, the political ideology that asserts that America was founded to be a Christian nation. Although the majority of Americans still think that declaring the United States a Christian nation would go against the U.S. Constitution, studies found that most Republicans would be in favor of this change.

Roughly 85 percent of Guinea’s population is Muslim, primarily of the Sunni school. Muslims constitute a majority in all four geographic regions. Christians, mostly Roman Catholic, comprise an 8 percent minority and are situated primarily in Conakry and eastern parts of the Forest Region.Other Christian denominations include Anglicans, Baptists, Jehovah's Witnesses, Seventh-Day Adventists, and various evangelical subgroups. Approximately 7 percent of inhabitants, located principally in the Forest Region, adhere exclusively to indigenous religious beliefs. Islam was introduced in Guinea in the 17th century in what is now the country’s northeast. Starting in the late 1720s, the Fulani ethnic group established a theocratic Muslim state in the mountainous Fouta Djallon region. The Fulani created an ethnoreligious social hierarchy which relegated non-Muslims to the lowest rungs of the social ladder. Though the state was ultimately assimilated into Guinea-proper, the Fulani have remained the country’s most ardent Muslim population, ahead of the Mandinka subgroup of the Mandé people. The non-Muslim Soso people were gradually pushed out of the Fouta Djallon due to Fulani oppression. The majority migrated to coastal parts of Lower Guinea between the 17th and 20thcenturies; an area comprised of the prefectures Boke, Boffa, Conakry, Coyah, Dubreka, Fria, Forecariah, Kindia, and Telimele. Roman Catholic missionaries made inroads into Soso communities following their (the Soso’s) establishment of trade ties with Europe. Many Guinean children, particularly in the Fouta Djallon region attend Islamic schools, which combine the government’s secular curriculum with Quranic studies. More devout Muslims student may enroll at a madrassah, or mosque school, which typically forego French for Arabic as the language of instruction, and adhere exclusively to a religious studies curriculum. Though Guinea’s constitution guarantees religious freedom, Islam enjoys demographic, social, and cultural dominance. In the past some Guineans have claimed the government favors Muslims in its policies, citing the cancellation of classes at publicly funded universities in accommodation of Friday prayers. Despite these and other reports of social discrimination against non-Muslims, religious freedoms are generally respected in the country.

Additional information on religion in United States prisons

The religious affiliation of inmates in the United States, the country with most prisoners per head globally, is reasonably similar to the religious affiliations of the society overall. That said, the proportion of non-religious inmates and those declining to express their religious affiliation is smaller than the overall proportion. In contrast the number of Muslim inmates is disproportionately large in comparison with wider society. As a result a sizable share of prison chaplains identity as Muslim, catering to the preferences of the Muslim prison population.

Following the September 11, 2001 World Trade Centre attacks and the subsequent War on Terror launched by George W. Bush, religious extremism has been a target of public debate and policy. The debate has stretched into prisons particularly with the United States prison on Guantanamo Bay holding a number of suspected terrorists related to religious extremism. In turn, fears have been raised that prisons have become a hotbed for religious extremism.

Critics have argued that religious extremism has provided an unwarranted justification for the conviction of Muslims. Regardless of the supposed reason for their imprisonment, this disproportionate number presents a problem for United States policy makers.
