The God Delusion

Good points. That covers the main reasons for my atheism, just about.

About the book by that title:

I read it, and I thought that it wouldn't be very convincing to someone who wasn't already convinced.

But, since I am someone who's already a hardcore atheist, none of the arguments in the book were anything new that I hadn't heard already before.

I think the only audience who'd find the book useful and compelling would be those who are just on the cusp - people who are in the process of losing their religion, or people who've begun to have serious doubts about their religion and are looking for help in clarifying their thoughts. I think I would've loved this book a decade ago when I was seriously questioning Christianity.

I guess it's a very good book on Basic Introductory Atheism 101. It's a good book for anyone looking to understand why someone would be an atheist.
