I felt like you do for a long time. But as the years have gone by I have been able to look at the organisation more objectively and my eyes have been opened more and more. Any lingering belief that they just might have the "truth" faded when I read Ray Franz's book: Crisis of Conscience". The book is so well written, not bitter or nasty, and just points out facts about how the organisation works. I now know that the JW's are no different from any other religious organisation, despite their claims to being "different" from the world, and I no longer live with the fear that I might be risking my childrens lives by not going to meetings etc!
I also know that there are many, many good, genuine JW's (my parents being two of them - elder/pioneers have devoted 45 years to the organisation) but they have been sucked in by an organisation controlled by people who are very clever and manipulative.
