Yup, the only thing more delusional that JWs believing in an eternity spent petting pandas is the apostate who thinks his rant-filled "Bring Down The WT!" campaigns will have some sway on people actually leaving, as if he's a Don Quixote who's tilting at evil dragons (when he's actually tilting at windmills). Such efforts likely only REINFORCES and VALIDATES the beliefs of those still in, which actually strengthens and serves the purposes and interests of the group they claim to be trying to "topple".
As stated, usually people are seeking validation for whatever beliefs they already hold, in the JWs or out: in the case of joining the JWs, the immediate situation may be as outlined above (i.e. the death of a loved one, etc), but their presuppositions are going to set them up to join the JWs (eg believing in a God, the Bible, Christianity, distrust of humanity, hopelessness, poor education, etc). The preaching work of JWs is actually not spreading the message to convert, but simply locating those individuals who are, for whatever reason, likely to accept it, AKA pre-acceptors.
The same goes for leaving the JWs: most individuals need a "push" to convince them to change from their beliefs and to seek out TTATT, be it receiving an unfair reprimand over some silly infraction (and the account of an female getting accused of 'loose conduct' on the basis of appearing in someone else's dream and doing a lap dance takes the cake, if the account is true!), all the way up to getting DFed for committing unrepentent pedophilia (!). Both individuals are likely 'licking their wounds' and seeking to rationalize their treatment, and will find consolation after being willing to actually look at the evidence that supports TTATT.
JWfacts.com comes to mind of the kind of, "just the facts, only, Ma'am" approach that is most-likely not to be rejected or dismissed, since most believers don't need ANY ASSISTANCE looking for excuses to confirm their biases against 'apostate' thoughts; the ego of the messenger is likely only a hindrance to others accepting TTATT, since again, if they joined the JWs, the person likely already accepted the idea that someone who is calm and friendly is a more-likely source of truth (yet another permutation of the "style over substance" fallacious thinking).
Kinda sad that it takes coming to such extreme conditions for some people to face up to reality, but it's better late than never, I suppose...
