So unbelieving relatives undermine JW morals. Seems to me that their believers that practice adultery, bully the flock, shun people who do not share their beliefs, live off benefits and practice child abuse are more likely to undermine the morals of their congregations rather than the normal balanced people on the outside.
Isolation and pressure on children is a worrying development. This has been implied and baptism of pre teens has been lauded but has not been described as the norm before. The poison is that because this has been said by a member of the GB it carries more weight with the congregation. So from infancy they have to have the identity as a JW so that as juniors they can get baptised so that as teenagers they can be shunned.
I feel for witness children unable to talk about sports, or food and driven into a harsh faith before they can truly know the consequences of their choice.
