I firmly believe that most JWs can't reason and defend their religion anymore. Heck, the whole org can't defend itself anymore. More and more it's becoming such that JWs less and less know their own history and their own beliefs.
They're really in a catch-22. It doesn't take a brilliant mind to realize that the JW prophetic framework failed. Everything JWs were promised didn't come true and has been replaced by overlapping generations nonsense and "wait on Jehovah" platitudes.
So the religion needs to rethink and make wholesale changes to its doctrine and prophetic structure.
Yet to admit this and move forward on that plan is to admit that they don't really have the truth and aren't God's special people.
They can't make the changes that are desperately needed without conceding defeat, so instead we've had this 20-year long period of stagnation hoping that somehow the things they believe in come true even though there's no signs of that occurring anytime soon. Meanwhile, I've seen my parents generation who came into this religion with young families grow old and die. Wasted lives, no retirement plans in place.
It's sad.
