Star Tiger, I think you have the right idea. This is the sort of approach that helped me break from the JW mentality when I was a teenager. I started by reading 'blasphemous' philosophers like Nietzsche. I went to different places of religion like churches and a Buddhist temple (that was actually very pleasant, and led to a deep interest in eastern religion). I played around with some tarot cards and saw the 'Exorcist'. I guess everyone's barriers are different. Basically I broke down my barriers so I could build up a new kind of spirituality, one that was based off of authenticity rather than fear.
