Has anyone discovered a successful way to make religious people atheist?

Encourage people to go read their holy book.

Properly read it. Not cherry pick the bits they've been told are the important parts.

The bible especially has been the number one book for creating atheists. Christianity survives because of people's general apathy towards reading it. They make huge assumptions about it, and actually reading it can sometimes shatter them.

The advantage of this strategy is that it's hard for the theist to object. It's more than likely what they are telling you to do too, at some point in the debate!

I'm not suggesting harassing random theists into doing this of course. You're almost certain to fail by getting in someone's face, about anything.
