The World Atheist Convention in Dublin adopted the following declaration on secularism and the place of religion in public life.

1. Personal Freedoms
(a) Freedom of conscience, religion and belief are private and unlimited. Freedom to practice religion should be limited only by the need to respect the rights and freedoms of others.
(b) All people should be free to participate equally in the democratic process.
(c) Freedom of expression should be limited only by the need to respect the rights and freedoms of others. There should be no right ‘not to be offended’ in law. All blasphemy laws, whether explicit or implicit, should be repealed and should not be enacted.

2. Secular Democracy
(a) The sovereignty of the State is derived from the people and not from any god or gods.
(b) The only reference in the constitution to religion should be an assertion that the State is secular. (c) The State should be based on democracy, human rights and the rule of law. Public policy should be formed by applying reason, and not religious faith, to evidence.
(d) Government should be secular. The state should be strictly neutral in matters of religion and its absence, favouring none and discriminating against none.
(e) Religions should have no special financial consideration in public life, such as tax-free status for religious activities, or grants to promote religion or run faith schools.
(f) Membership of a religion should not be a basis for appointing a person to any State position.
(g) The law should neither grant nor refuse any right, privilege, power or immunity, on the basis of faith or religion or the absence of either.

3. Secular Education
(a) State education should be secular. Religious education, if it happens, should be limited to education about religion and its absence.
(b) Children should be taught about the diversity of religious and nonreligious philosophical beliefs in an objective manner, with no faith formation in school hours.
(c) Children should be educated in critical thinking and the distinction between faith and reason as a guide to knowledge. Science should be taught free from religious interference.

4. One Law For All
(a) There should be one secular law for all, democratically decided and evenly enforced, with no jurisdiction for religious courts to settle civil matters or family disputes.
(b) The law should not criminalise private conduct because the doctrine of any religion deems such conduct to be immoral, if that private conduct respects the rights and freedoms of others.
(c) Employers or social service providers with religious beliefs should not be allowed to discriminate on any grounds not essential to the job in question.

It seems well thought out and leaves little to quarrel with. As a matter of fact, I only have a few peeves.

4.(c). It implies that employers or social service providers without religious beliefs should be allowed to discriminate. The entire point could vanish and have no impact. We do not want any discrimination at all, religious or otherwise.

4.(b) poses problems too. I agree with it 100%. That doesn't help. Let me give you an example. In secular humanism, which is the philosophy this manifesto espouses, humans reason their way from emotion and ego warped values to policy and law. If, for example, bestiality turns your stomach, you can reason and rationalize a legitimate framework for a law banning it. You may not just say "God forbids it." But you can still find a way to make a law against it. If it tickles your fancy to molest a moose, you can reason and rationalize a way to add it to your bill of rights. In the end, it is your values, not their source or your rationalizations that count. If you have a population that is 60-80% Christian, that is going to influence their values. Would you simply ignore the values of the majority because you can claim it is derived from religious dogma?

3.(b) ends with "with no faith formation in school hours." I feel pretty certain that the people who wrote this know it is hooey. There is always faith formation. What they are driving to is a formation of faith that nature operates without the influence of the super natural. Let's face it, that is the distinction between religious and secular education. Whether we operate in a framework of laws driven purely by nature or a framework that includes the effects of the supernatural.

1.(c). "There should be no right 'not to be offended' in law." Offensive behavior is disruptive to peaceful and orderly society. That is why there is a generic 'disorderly conduct' law on the books all across America in every jurisdiction. In America, the 1rst Amendment is limited by several constraints that have nothing to do with religion.

Overall, it's the best declaration of it's type that I have seen.
