Hi Alanb and welcome.
All it would take would be the exposure of the true nature of the WTBTS religion. For example the devasting effects on people due to their various doctrines on child abuse, blood, shunning etc, the true nature of which remain hidden until one is baptized and fully involved.
No it wouldnt fulfill any bible accounts as these require a turning on ALL religions by the wild beast.
I could go on but I dont wish to hijack this very important thread.
Please feel free to PM me.
