Same as reading Hitchens / Dawkins / Harris etc. Only people who are already of that opinion tend to pick up those books where as the people who actually SHOULD read them tend not to. All they really do is give the non-believer a slightly sharper arsenal of tools with which to state their cases.
I am. I think if you can make someone who hasn't read these authors laugh or question for a second while showing them in your own person that an atheist can be quite happy, fulfilled and humane and, at the same time, demonstrating that religious people frequently live in fear, and kill each other over abstractions you can sow seeds, these people may check it on youtube and if they like that read about it.
Nobody may have questioned them before.
I like the 3 of the 'horsemen' but I think Hitchens is a bit of a dick
