A lot of focus has been put on JWs’ treatment of minors in regard to disfellowshipping, but the actual case in Norway is just as much about the policy of shunning of any former members who wish to leave the denomination. This is especially relevant to ‘apostates’, though individuals who are disfellowshipped for any reason are still shunned, with only a slightly relaxed policy that only really amounts to additional emotional coercion to ‘return’.
The policy, along with pressure from the organisation, to shun ‘apostates’ is also quite separate to the rights of individuals to stop talking to someone as an individual choice. But it is by design that members are officially not allowed to talk to dissenters, and making shunning a ‘conscience matter’ would defeat the purpose of the ‘arrangement’.
