Phizzy: The change I have observed is that many new Posters seem very naive and
lacking in a lot of knowledge, even about the Bible and the religion
they are leaving.
When I joined the JWs in the early '80s, there was at least the pretense or illusion of approaching religion and a study of the Bible from an academic or scholarly perspective—albeit not a real one from a rigorous, academic point of view.
This religion has become so dumbed-down that it is really embarrassing. This is why we no longer need to get involved in any deep, theological debates or discussions.
The WTBTS has had a long, slow-burn to get to the present simplistic belief system that they currently espouse. But they really jumped-the-shark when they published their ridiculous "Overlapping Generation" interpretation of Matthew 24:34.
The downhill descent from there has only accelerated exponentially.
One quick look at the current leadership only confirms how intellectually bankrupt they are, with of course the main Poster Child for that being Stephen Lett:

I mean, seriously! Who would, for one second, think you could have anything even remotely resembling an intelligent conversation about anything with that guy?
