The organization has used anti-apostate propaganda to give JWs a phobia for apostates so that JWs will not get the inconvenient truths about the organization from apostates. It's classic case of Watchtower using BITE. They're using emotional control (fear of apostates) to effect behavior control (not listening to apostates) to effect informational control (prevent JWs from getting damaging information about the organization).
Deception requires ignorance on the part of the decieved. The more differing sources of information that a person has on a matter the less likely he is to be decieved. When one listens to only one source on a matter - especially if the information provided by that source is favorable to the source (conflict of interest) the more likely he is to be deceived by that source. Can you imagine a court where the judge instructs the jury to listen only to the defence and to cover their eyes and ears so as not to see or hear anything the prosecution has to say? Well that's the idiotic position of the Watchtower when it tells members not to see information from critical sources and apostates. They behave just like authoritarian regimes that censor critical news reports from getting into their police state.
Emeth: As soon as former JW's turn into anti-jw activists i would not mingle with them in real life. Why should i do that with people who have started to hate and despise the thing that i love?
Emeth, what if I told you that I hate your favorite food? Would you refuse to mingle with me because of that? Will you shun me because of that? That would be foolish, wouldn't it? But if you did do it to me, guess what? I'll be thinking to myself: "What! You're not speaking to me just because I don't like your favorite food?! I can't believe this! Emeth, you're a total douche bag!" I might be so upset and indignant about your childish action that I would tell others about it. "That Emeth is a real moron! Can you believe the guy is shunning me just because I told him I don't like his favorite food? Unbelieveable!"
So you see, Emeth, ironically one of the reasons why JWism is so hated is because you shun ex-JWs simply because they no longer believe your religion. If you would allow people the dignity to leave without shunning them and disparaging their character then ex-JWs would have less reason to speak out against you. It is the Watchtower's childish and vindictive policies that inspire ex-members to become activists against them. You (JWs, the Watchtower) are the root of the problem. You are your own worst enemies and seemingly too blind to see it. Or do you see vocal ex-members of normal non-vindictive religions protesting against them? No. It's only the ex-members of authoritarian and vindictive cults that do that. You reap what you sow.
