Convert a religious person to become an Athiest

Over the years I have probably played a role in a few friends religious views as I am quite vocal about baby jesus. See, I recon if I have to hear about him all bloody day long, the religious should play fair and accept a bit of it back. This goal is now marked as complete as one of my friends, whom originally was quite religious, has recently described himself as not quite the follower.

Because they keep trying to convert me—without one iota of success
