Apog: Not sure I see the problem here.
What does WT drum into every JW as to being present for the entire meeting or assembly program? Do not miss the song and prayer because these two components are a vital part of our worship.
Yet, in Mexico, WT was willing to dispense of these vital components and went a step further by also doing away with the Bible itself !!
This isn't a problem?
What would happen to an individual JW who on his own refused to sing songs at the KH, refused to participate in prayers and refused to use the Bible?
Most certainly they'd be disfellowshipped under some charge of "brazen conduct" or disrupting the peace of the cong. But in true hypocritical WT fashion, when the GB decides unilaterally to dispense of its own self-claimed "vital" aspects of worship for no other reason than to protect its corporate/financial interests, suddenly the heretical becomes acceptable.
