I've was a fundamentalist for ten years. I've been an atheist for the last 17 years. I now work in mental health services and specialise clinically in working with delusions.
I've just posted two blog entries summarising the delusional nature of religion and my own journey into and out of fundamentalism. I thought you might find them interesting.
The links are here. Please feel free to post them on your site if you wish, either by posting the links or cutting and pasting the articles themselves into another document.
