The WTS. had arranged doctrines to support one another conceptually such as the year 1914 and this generation, to the final day of judgment Armageddon.
Well nothing happen of course so the WTS heads (GB) had to created another false doctrine to cover over their previous false doctrine, this was the overlapping generation .
The WTS supported itself upon bullshit theology it created as to create an acknowledged identity for themselves (FDSL) and help to proliferate the literature the organization published.
.......they are still bullshitting to this day..... why ?
Becasue that's how the organization was built and structured on.
Why are there so many JWS not wanting to accept that they have been conned is very much to do with this organization's highly controlled cult aspect ?
If one were to opening criticized the doctrines you could find yourself demonized, shunned, experience a total loss of friendship by other JWS members , including your own active family.
