My thinking is that this group has the 'truth' because thats what they are told and understand nothing. I was the same way...and actually stumbled on this website after googling the JW dot org ridiculousness and found a picture that linked me here. It was after reading a few posts alone, I was beyond shocked. All the feelings I had were shared-- then I read about 1914 etc... Wow.
I think the only fear is losing family and friends for this group- the end is near propaganda isn't going to work.
