Hi Justin,
The one main practice that causes so much pain that is rather unique for the JWs is disfellowshipping. Many other religions have somewhat simmilar desires to control your lives by some inspired book, but the practice of isolating your family is so evil and hurtful.
I think religious organizations waste so much of peoples time and money. Have you noticed when driving around how many church buildings there are and the money this must have cost the poor people attending? I prefer to let God just be a personal feeling of our imagination, since so far that's all the evidence we have. I agree that our family is the best place to spend our love and time. It gives real meaning to our lives along with our friends and other fellow humans(not just a small select group in an organization).
I don't spend my time trying to destroy religion, but I don't mind pointing out a few of the fallacies as the opportunity comes along.
I hope you enjoy your life with your family and friends as much as I do in my few remaining years.
Ken P.
