Great summary Terry.
Personally, I have come to conclude that ALL "religion is a snare and a racket" as Judge Rutherford explained in his books Enemies (1937) and Religion (1940).
On that basis the Watchtower is definitely a front-runner.
They push religion to the max (apostate legalism, apostate moralism, supremacist ethnocentrism/doctrine, supremacist religious Gnosticism).
Therefore for me the Watchtower is indeed one of the TRUEST snares and rackets (religions).
No religion I know of, has accomplished more in telling their followers they are "publishers of the Good News" whilst deliberately keeping them ignorant of this same "Good News".
