Religionism

Religious discrimination treating a person or group differently because of what they believe in. Specifically, it is when adherents of different religions (or denominations) are treated unequally, either before the law or in institutional settings such as employment or housing.

Religious discrimination is related to religious persecution, the most extreme forms of which would include instances in which people have been executed for beliefs perceived to be heretic. Laws which only carry light punishments are described as mild forms of religious persecution or as religious discrimination.

Even in societies where freedom of religion is a constitutional right, adherents of religious minorities sometimes voice concerns about religious discrimination against them. Insofar as legal policies are concerned, cases that are perceived as religious discrimination might be the result of an interference of the religious sphere with other spheres of the public that are regulated by law (and not aimed specifically against a religious minority).

In a 1979 consultation on the issue, the United States Commission on Civil Rights defined religious discrimination in relation to the civil rights guaranteed by the Fourteenth Amendment to the United States Constitution. Whereas religious civil liberties, such as the right to hold or not to hold a religious belief, are essential for Freedom of Religion (in the United States secured by the First Amendment), religious discrimination occurs when someone is denied "the equal protection of the laws, equality of status under the law, equal treatment in the administration of justice, and equality of opportunity and access to employment, education, housing, public services and facilities, and public accommodation because of their exercise of their right to religious freedom."

However, cases of religious discrimination might also be the result of an interference of the religious sphere with other spheres of the public that are regulated by law. Although e.g. in the United States the Free Exercise Clause of the First Amendment states that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof", in Reynolds v. United States the U.S. supreme court decided that religious duty was not a suitable defense to a criminal indictment. In this specific case a law against bigamy was not considered to be discriminating against Mormons, who stopped practicing Polygamy in 1890.
