In Australia we have anti bullying laws in organisations. Shunning and exclusion is included in these laws. The only problem is that religious organisations are exempt from these laws. if we have anti bullying policies for work and school then this should also extend to religions. Jehovah's Witnesses and Scientology and any other harmful cult should be threatened with loss of charity status and tax exemptions if they don't comply with basic human rights. if they want to mandate shunning sure go ahead but the government should not subsidise or give tax exemptions to them. If watchtower uses coercion so can the government 😉.
Oh as for media not being interested in the shunning policies of Jehovahs witnesses, I disagree.... Keep your eyes open because there will be more exposure re shunning in Australia.
