If it's not the truth but you will deny life saving treatments to your children because it's a good way to live... because several blokes in Brooklyn decided this the last century.... then you are far from appreciating the alternate lives available.
How can one defend going to people's doors trying to convince them of something that isn't true, but you feel will be good for them? That would be outrageous!
With the JW religious denomination having the lowest wages and least educated members internationally (Pew study) alongside disturbing levels of paedophilia and decades of abuse risk, where is this 'good way to live'? Even there very own GB member told the Australian judge in the child abuse review case, live streaming to the world, that things were not good enough, safe enough for these kids in the JW's.
Therre are plenty of other belief systems that suggest, encourage or require clean living too, without so much known consequence/ harm to ones life.
Then there is the anecdotal evidence we have all seen, the stress and burn out of an uneducated group of people, striving to survive financially whilst also attempting to overcome perpetual guilt and spiritual demands. The congs were full of depression, stress and burn out. Bethel was, more so!
