The two big fears they promote are those of Armageddon and of sinning against the holy spirit.
PaintedToeNail: " To this day, I cannot watch doomsday or armeggedon type movies, it induces panic attacks and horrible feelings of dread!" I can certainly relate to this. I have had reoccurring nightmares of a storm coming in the distance since childhood. The storm, of course, represents Armageddon.
The other fear - that of sinning against the holy spirit - was drummed into my head by my dad. This actually backfired, as I thought to myself, If I've already sinned against the holy spirit and there's no hope for me, then I might as well check out the "apostates" on the Internet - which is exactly what I did. Fortunately that worked out in that I was able to peak at the "man behind the curtain" and see the whole JW thing in a completely new light. Yes, that particular phobia can certainly end up backfiring on some people, producing yet another "apostate" - which can end up being a sort of "thorn in the flesh" for them.
