Just to whet your appetites, here's an extract from near the end of my article/essay, "Atheists for Freedom of Speech":
Atheists and religious sceptics have good and urgent reasons to challenge the authority of religious organisations and leaders to pronounce on matters of ultimate truth and correct morality. None of these organisations can speak for a superior being, such as a god, with a claim to our obedience or deference. The emperor has no clothes, and we ought to say so. In particular, religious leaders are not moral leaders, much as they might pretend to be. Their non-existent credentials ought to be exposed. This will require persistent, cool argument, but also moments of outright denunciation or unashamed mockery of religion's most absurd actions and truth-claims. In particular, we should not flinch from expressing the view that no religion has any rational warrant, and that many churches and sects promote cruelty, misery, ignorance, and human-rights abuses.
