Secular Coalition For America is an advocacy group located in Washington, D.C., representing atheists, humanists, freethinkers, agnostics, and other non-theistic people with a naturalistic worldview in American politics.
The Secular Coalition works to increase visibility and respect for non-theistic viewpoints in the United States and to protect and strengthen the secular character of the U.S. government. The Coalition advocates complete separation of church and state within American politics which they claim is clearly established in the U.S. Constitution under the First Amendment. They point out that freedom of conscience, which includes religious freedom, was of such importance that it was made the first of all freedoms protected in the Bill of Rights. The Coalition holds reason and science as it guiding tenets for public policy.
