I don't think JW's create atheists as much as breaking free from the cult mindset makes one hypervigilant against other cult-like programs that religions in general practice. (Anony Mous)
Atheists are not created by anybody. (Trevor)
the Watchtower Society actually isn't responsible for "making" me an atheist... (Ziddina)
I can't really argue against any of your sentiments. If we are truly free to make up our own minds, only we are responsible for becoming what we become. But creation of self does not occur in a vacuum. Many Jehovah's Witnesses believe what they believe because their parents believe what they believe. It is fair to say that they are not entirely responsible for what they are and that the Society has played a hand in creating their mindsets. In a broader sense, most people who profess to be Christian happen to have been born into environments that embrace Christianity. Had they been born in Afghanistan they would almost certainly profess to be Muslim. Yes, someone who becomes atheist or agnostic after having abandoned a previous faith in god is a little different, but more likely than not his transformation is a consequence of many inputs, some of them direct and purposeful, some entirely accidental. My association with the WTBTS caused me to examine faith at a much deeper level than I would have otherwise. This I cannot deny. Without that particular influence I might reasonably expect to have settled into some sort of pragmatic agnosticism - believing in things for which there is strong scientific evidence, like the evolution of species, but leaving the door open for there having been some kind of divine influence. The Watchtower played a hand in closing the door.
