What a balanced reply. Well thought out and reasoned.
There are so many things we could get involved with that are far worse than a religious cult. What about the Manson Cult? What about the bloodguilt of the Nazi's etc. It doesn't mean that the religion didn't do us harm but we can stop that harm in time.
Our motives while we were JW's were pure for most of us and we had a real desire to help others and to worship God. There are probably about the same number of Christians among JW's as many other religions.
How right you are about the black and white thinking. We need to stop it!
