I enjoyed the interview just now with Hilary Joy. I don't know a lot about 94.7 The Pulse ... but it looks as if you will be able to hear the interview by podcast at some stage if you check out its site now and then. We were talking mainly about the propensity for religious organisations - not necessarily all of them, but all too many of them - to try to prevent criticism of religion, while at the same time they attempt to impose their specifically religious moral views through political power.
I tried to make the point that religious organisations often support "freedom of religion" in the sense that political power will not be used to control their activities. They are, however, not necessarily interested in secular government, i.e., political power being used only for worldly purposes such as personal and collective security and economic welfare. All too often, there are attempts to impose religious conceptions of sinful and righteous conduct through the operation of the law. Thus, we need to be very careful about what is meant when we hear religious organisations and their leaders claiming to support "freedom of religion".
This is, of course, a theme of Freedom of Religion and the Secular State. I didn't get a chance to plug the book in the radio interview, so I'll do so again now. The segment did plug Warren Bonett's excellent edited book The Australian Book of Atheism (which includes my article, "Atheists for Freedom of Speech").
