When I was first out for good, I really wanted to bring the WT Org down, to free my JW family, and to be truthful, as revenge for my stolen life.
Now I see that there is no way to bring it down, they are impervious to most onslaughts, some, like expensive lawsuits hurt their pocket, but they are not going to cause the Org's demise.
Even though the numbers must be falling in terms of real growth, I believe that really they are just about replacing those that die and those that leave, and even though the numbers may in fact go into "reverse" in the not too distant future, this will not free the really indoctrinated JW.
So we have to face it, our families are probably going to stay in.
It will gradually wither and die, but I reckon another 50 years is needed for it to be almost gone.
Of course, even at 8 million or so as at present, they are still an insignificant weird little cult.
They really do not matter.
