From the Atheist Revolution blog comes an entry about how to communicate what is wrong with religion.
It contains a link to a post on the An Apostate’s Chapel blog.
There the chaplain does a really good job of laying out three fundamental (can I use that word?) problems with religion:
The first problem that I have with religious beliefs is that … acting on the basis of false beliefs can lead to ill-conceived, even harmful, behavior and decisions.
The second problem I have with religious belief is that believers do not live in vacuums. Their religious beliefs are not always private and those beliefs do affect others, including me, in numerous ways.
The third problem I have with religious beliefs is the persistent entreaty that I respect religious beliefs simply because they are religious.
Well worth going and reading.
