Sometimes generally referred to as "the nones," agnostics, atheists, humanists, freethinkers, secularists and skeptics compose one of the fastest growing faith categories in the United States. Because they are treated as "nones," some people face discrimination as nonbelievers, despite their varied and strong beliefs, values and morals. This basic guide, "100 Questions and Answers About the Religiously Unaffiliated," describes the differences, explains why discrimination and laws force some to hide their beliefs and why they would like to shed the label of "nones." Religious freedom and the First Amendment's establishment clause come up frequently.

The key issue for many is whether the First Amendment's guarantee of religious freedom also guarantees the right to be free from religion.

Legal issues include school prayer, the obligation to support tax-exempt religious properties and requirements that people profess belief in God to be allowed to vote or hold office.

Life magazine called Madalyn Murray O'Hair, whose lawsuit ended mandatory prayer in public schools, "the most hated woman in America." The Secular Coalition for America's website directory withheld the name of its communications consultant because "unwarranted prejudices and discriminatory practices ... affect atheists and humanists. Consequently, s/he felt it was best to be incognito for now, since working for an organization that protects the rights of nontheists might result in lost opportunities with other clients."

In this guide's forward, Dr. Phil Zuckerman writes, "Understanding secular people is important for many reasons. For one thing, secular movements, leaders, values and ideals play significant roles in the political landscapes of the world. From the first sentence of the First Amendment to the U.S. Constitution, to Article 20 of Japan's Constitution, from France's laicite to Vietnam's atheistic dictatorship, and from the founding of the Mexican Republic to India's current political struggles, in many countries secularism is a central pillar of both stability as well as conflict.

"Additionally, secular men and women are often unjustly stigmatized as immoral scoundrels or angry curmudgeons - negative stereotypes that don't actually accord with reality yet prove to be both persistent and pernicious. For instance, in some societies, such as Saudi Arabia, Pakistan and Malaysia, hatred and fear of the secular is so strong that those who don't believe in God can be imprisoned, tortured or even executed. Here in the United States, many state constitutions - such as those of Tennessee, Texas and Mississippi - currently outlaw anyone who doesn't believe in God from holding any publicly elected office."

Dr. Morgan Shipley's introduction says, "For the more than 85 million Americans who identify as nonreligious, we witness a turn to secularization as both an explanation for the lack of belief and a source for fulfilling the areas of life commonly associated with religion, such as morality, togetherness and agency. For the nonreligious, then, we find more than a rejection of God and faith. Instead, we uncover various ways humans highlight virtue, pursue a sense of belongingness, celebrate progress and rely on rational discourse to construct meaningful and morally driven lives."
