How to Help Promote "The Christian Delusion" Book
Tell other people. Do this in your skeptic meetings. Tell your family and friends. Tell your former pastor. Tell a Christian apologist or two you may know. Write about it on your blogs. Quote from it in your online forums. Buy up copies to hand out. Rather than merely argue with your Christian family and friends, hand them this book. It will save you months of arguing with them, and it's not expensive at all. Donate one to your local library, or tell librarians it's something they should get. Go into your local bookstores and ask if they have this book. If they say no, ask them to order it. Have a couple of people do that and the bookstores will order the book. Ask one of the authors to come speak at your group. Check to see which author lives the closest to you. Interview the authors on your podcast if you host one. Write reviews of it on Amazon and other online bookstores.
If you are passionate about Christianity it's the least you can do for our common cause.
