My first experience with anti cult views was probably field service. We went out in service a LOT. We lived among a very educated population. Many of those people liked to get in long discussions about philosophical/theological issues, often for their own entertainment I think, and I still remember many of the conversations. It's interesting, because of course you are SUPPOSED to go out in service and have discussions with people, but doing that exposed me to all sorts of interesting ideas :).
So, I followed along with my parents, trying to be a good kid but always, always doubting. Eventually I hear indirectly that my cousin has slowed down going to meetings because, nope, it's not his job craziness like he excuses it to be, it's actually that he doesn't really BELIEVE IT. Whoa! Shocker! Someone in the family who doesn't really believe it!! I think this made it easier for myself to admit my own doubts. Still, when I researched a particular issue I was going through, I COVERED THE COMPUTER SCREEN with my hands, to try to filter out any apostate stuff I didn't need to see, and tried to keep my eyes on just my particular issue.
When there were signs outside the DC, I would say to myself 'just look down, don't read the signs, JUST LOOK DOWN!'
For me, it was doctrinal issues that made me take the big step. Otherwise, I was going to go along. Simply reading the New Testament instead of listening to the circuit assembly one day, I finally found Christ. I couldn't stay in any longer. Just in time too, before any of my kids were baptized. The first Ttatt fact I learned was about Beth Sarim. Sounded like Bethel, and I had never heard of it, there was an article in he 30's in LIFE magazine about it, and it WASNT IN THE PROCLAIMERS BOOK?? What???
