This site has helped me to let go of the guilt and "loaded language" that the WT has used to manipulate me in the past. It has also given me relief not to be in fear of Armageddon. I don't have to worry about the fates of good people who aren't JWs.
Most of the time this site is a definite positive. You have to take a few bad apples here with a grain of salt, though, just like anywhere. Some people cross the line but they are a minority.
The board hasn't destroyed my faith in a higher power, either, even though a lot of atheists post here. I still have affinity for the teachings of Jesus without feeling any organization has a monopoly on God. But I don't limit my spirituality to Christianity alone and enjoy posts by others who, like me, are open to other forms of enlightenment like zen living. And I don't condemn atheists because I can somewhat understand why they are where they are in their life.
It's a great feeling to be able to talk about all those WT things that have been bottled up for years with people who understand.
