Wow, so many good comments.
aChristian makes a good point. His option is from one who is well grounded in a faith. He knows where he stands and he has no question about what is real and what is not. To take such a stand is admirable and if I had been as well grounded to "my truth" back then as I am now I would have done exactly what he suggested. Stood and spoke my piece in order to show that I had no more fear from the JW teachings of fear. This would have an effect on others and my family.
However when I left, I was so indoctrinated and had little faith in myself or in God I would have not been able to stand up on my own and shout anything. It wasn't untill age 30 or so I even got a direction really and began to build a new faith in myself and later in Spiritual persuits and in God, many years after I had been out and deprogrammed the teachings of fear.
I do feel that someday down the road after you find your own path and want to pass some truth on to others, ie your kids, you may find yourself speaking out publicly for what you believe in, just as aChristian is doing. However the important thing is to survive right now! Consider which path for now will enable you to come to a point of personal love and respect for yourself. The JW's will always be there, how will you feel when you run into them?
How will it effect your family? Do you care what they think? It's easy to say we do not care but it is rarely true.
Thier control over you is directly related to how you feel, not what they do. You must find a balance that allows you to have self respect and grow, the other option can lead to suicide, so this is an important thing to face. The wound must be healed in you first and they will be there to reopen it if they can bring in doubts and fear.
Good Luck
