I wonder if some of the newer ones leaving may not have the same grasp of doctrine in general as some of the older folks?
I think some newbies may not care as much about actual doctrines but are more concerned with how leaving will affect their personal life and family relationships.
Definitely this.
The WTS members are way less "hardcore" than they were 30, 40, 50+ years ago. Back then it was all people searching for seeking answers and bible prophecy. Nowadays it's people looking for a lifestyle channel to follow. There's less investment and so less to walk away from.
The only consideration is the personal relationships because it was rarely about genuine "belief" because who believes shit anymore? It's about "your truth" and "your experience" after all, not absolute truth.
