People rescue themselves, they are the ones that wake up and start questioning things - typically in response to something that the WTS has done to them, or something they have seen in their local congregation.
How many of us got out after seeing or hearing a random comment that required additional research? One of my Elders was telling me about what an idiot he was in 1975 telling his coworkers goodbye for the last time during Christmas. That was 23 years ago. The internet being fairly new to my area, I had to know more. I looked at what Randy Watters had on his former website and then compared it to a random AOL site from a guy in Canada. A few stops through Geocities and then to here and I had all the information I ever needed. Without a doubt that is the journey each of us takes, just the questions and places change.
