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.
