I guess that one odd curious individual must have turned up at some point over the years somewhere...surely? Ahh! that must have been Mr Ron Scratchings of Wilmslow, myopic and a bit deaf who in April 1953 thought he was attending a Baptist meeting.
The reality of the public talk is that it is a JW ritual. Rituals give the believer the chance to demonstrate fidelity to the cult. In turn this creates a sense of belonging and consequently an identity. The secondary function is the talk script supplies a means of hammering home and battening down the JW doctrine into the hearts of true believers.
It is the opportunity to take on board the standard false arguments of why the JW org is always right and every other religion is from Satan.
Who else would willingly want to listen to dull Watchtower rhetoric apart from the already committed? Same with the WT study; dull recycled garbage lacking in truth or having any content value at all. Ideal stuff for the die-hard, lobotomised JW zombies.
Btw, well done to all those public speakers who with compassion tried to invigorate the propaganda with a semblance of warmth and humanity. Total waste of time though!
