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

 And I agree with what you're saying about cognitive dissonance, but that takes place usually when a deeply held belief comes under attack. 

I would think religion would be a deeply held belief no? If it's not, if your a "weekend" theist then your probably on your way to atheism anyway.

And you don't think arguing with "non-weekend" theist about their theism, be it civil or even lighthearted, doesn't qualify as an attack on a deeply held belief?

If your casually theistic your not broadcasting it, your probably not paying any attention to it. Therefore you probably don't come into any encounters where you have to defend it, or if you do you probably don't care much to defend it.

However if your not the above I think cognitive dissonance is in play.

Im just giving you my 2 cents. No matter the person, if they feel threatened they'll usually react defensively. In harmony with you OP, I strongly believe that any theist, strong or weak, needs to feel like they're not under attack
