Do we want to convert the religious? Should one of the primary functions of organizations such as the Council for Secular Humanism and the Center for Inquiry be to persuade the religious to abandon their beliefs? To answer these questions properly, we should first ask: What objectives would be served by converting the religious?
The exact nature of religious belief varies from person to person but usually involves commitment to the existence of a supernatural reality, including a deity. We who are not religious have (presumably) examined the relevant evidence and have found it insufficient to support the claims of the religious as they relate to the existence of a being or beings that transcend the natural world. Simply expressed, the religious hold false beliefs.
