The attitude of some on here which I find annoys me is "Don't bother, it will make no difference, the JW's will not listen Blah Blah", how these anti-activists can possibly know the effect of whatever activists do is beyond me.
But I do believe that every thought you plant in a JW's mind, even if they reject it at the time, will bear fruit when they are ready,perhaps the seed will die with some JW's and they will remain forever trapped, but for me, if I can help just one person out, that is brilliant.
As an example of a thought that festers, when I was an active JW someone said to me "Your Jehovah is just a fictional character, made up by ancient tribes".
At the time I realised that I had no satisfactory answer to that statement, over time it ate away at my faith. Just a short pithy sentence, but that "Activist" made me start to think.
