I like Sunspot's restaurant analogy, I will give my own:
There are many restaurants in town, one restaurant in particular is the only italian restaurant in town, so if anybody is craving italian food they must eat there. The problem is this restaurant has been in trouble repeatedly with the health department over various complaints. The owner seems unwilling to change, and will only do enough to get by the scrutiny of the health department. The customers start to complain that the restaurant is unsanitary to the owner, however it falls on deaf ears. Now the people in this town love italian food so well that they are willing to put up with the less than sanitary conditions. When the customers start to complain more to the owner, the owner tells them to keep their mouth shut or they will be banned from his restaurant. Some people get pissed at the owners refusal to comply, and stage protests out front with signs that say "this restaurant is unsanitary" Some contact the local news media, and even some former employees go to the health department and inform them of the violations.
Then gradually this owner starts to see his business is faltering, he cleans it up really nice, and pretends to be within the health regulation. Some former patrons start eating there again, but business was never as good as it was in the beginning, Why? because the original customers will always doubt the sincerity of the owner. The owner knew all along his health practices were poisoning his customers, but he refused to to anything about it, and the only reason he finally did anything was a last ditch effort to save his business.
The business owner was shoddy and really couldnt be trusted.
See how all this compares to the WT Society? Even if the WT Society did a complete reversal on shunning, blood transfusions, and child molestation, could anyone ever trust them again?
For me the answer is no, because the welfare of the JW people is always secondary to the image and financial well being of the JW Cult.
They are liars, manipulators, and that is one facet that will never change with them, no matter what else they change.
