Who Says One Book Can't Change Your Beliefs?

Previously I had asked whether reading one book could change a person's beliefs (#10 in that link). Apparently it can (well two anyway):

Hey John, just wanted you to know that I threw 20 years of Fundamentalist Baptist Bible teachings away because of your books. Thank you! Your books introduced me to the truth that there were no answers and that Christianity was absurd to the core! I was just more embarrassed that I didn't see what you saw, but that's what happens when you go to Christian Schools, Churches, and Camps....you only get one side of the picture! --Tim Zajac on Facebook.

So long as Christian defenders remain silent about my books more believers will walk away from their faith. This is probably the reason why New Testament scholar Dr. Dale C. Allison Jr., wrote his Blurb about The Christian Delusion:

Forget Dawkins. If you are looking for a truly substantial, well-informed criticism of the Christian religion, this is your book. Defenders of the faith will do believer and unbeliever alike a disservice if they do not rise to the challenge and wrestle with the thought-provoking arguments of Loftus and company.
