98% of them appear as trolls and end up making complete arses out of themselves. Thats a good thing. In this case they serve as shining examples of the hypocrisy and intellectual bankruptcy inherent in the organization. They also remind of us as to why we left this wacko cult in the first place.
Having said that, I would say that the vast majority I have encountered on this site have been deliberately malicious and callously dismissive of the pain and suffering that so many people on this board have suffered at the hands of the borg. This serves no good purpose. Rubbing salt in fresh wounds is the worst possible thing that can happen to a person coming to this board genuinely looking for support. I have no tolerance for this breed of troll, and in reality, they form the majority of the trolls on this board. PMJ comes to mind.
While I more or less agree with Terrys comments I think they are far too generous. Based upon what I have observed, the apologists are NOT here due to unconscious doubts. They are here to either 1) make field service hours. 2) deliberately disrupt conversations and threads, or 3) engage in malicious attacks against watchtower victims.
Am I glad they are here? No. I dont need an "in vivo" reminder of the stupidity of the organization, those memories are indelibly etched in the darkest recesses of my memory.
