Smiddy: The rest seemingly have the attitude " I have tried the religion (some
after many years) decided for one reason or another it`s not for me ,
and walked away" , they have simply turned off religion and are just
not interested in talking about it anymore.(as they used to do when they
were witnesses)
I wonder if the ones who are the most vocal after leaving are the ones that really understood the religion the best. Many Witnesses don't get most of it; to them there simply is no immortal soul, no trinity, and no blood transfusions, and that's about it.
But the ones that took it more seriously understood the deeper issues such as what the Gentile Times meant, how 1914 was arrived at, what the 1914 Generation was all about, and the workings of the Organization. When the more knowledgeable ones discover it isn't the truth they have more to talk about.
Probably most of the posters on this site fit into the latter group.
Individual personality may have something to do with it too; some people are more vocal than others by nature.
As a side thought, I've always felt that the ones who never leave are the least knowledgeable. In other words, Watchtower is mainly losing it's best people, and the best ones will talk.
