Dear Professor Dawkins
Thank you for your bodies of work that have opened many people's minds to what they really believe in. It is a stretch to say I am converted as I was never hugely religious. But I did previously believe in god mainly because of what I was taught in school (which I think is wrong but is a different issue). If a persons whole belief system cannot stand up to simple questions then what benefit does it have. You opened my mind to think, look at the facts and come to my own conclusions. And when you do that there is only one genuine option left- atheism. I doubt you will read this but I just want to say thank you. It is no exaggeration to say you have changed many people's lives for the better.
(I just wish you sold signed copies of your books!)
All the best
