I have had a couple of big blow outs where I tried to expose the org for what it is. I used transplants/blood/failed prophecy/d/f policy. Because I felt so badly decieved myself I overreacted and it ended up in a fight. This brings no results whatsoever.
Now I just try and show that I live a good life. I try to show that most people in the world are also good, honest people who also have a level of integrity. I agree with the other post which mentioned trying to `win without a word`.
JW`s have the strangest look on their face when you inform them that you are happy and living a good life. You dont need to overdo/exagerate your happiness, just be humble and honest. They just cant understand it. If you said that you were miserable, depressed & utterly dejected, sad to say, they would be delighted. It goes with their mentality. We were all like this once.
By being a decent person (despite own personal weaknesses), you show that the crap you are fed about `the world being in wickedness` is nothing but an exagerated opinion. The more they see that you are not worthy of the death sentance at armageddon the more they will internally question what they believe.
Its sad for me to see loved ones in such a state of confusion about the twisted beliefs they have been taught but nevertheless it is a necessary process. I was there myself once, not too long ago.
Time & good living breaks down this thoroughly warped belief system. Unconditional love for all ensures your own happiness whatever JW relatives decide to do.
