Ozzie, l know what you mean . I only know about the WT from being on this site . It's taken me a long time to even try to get my head round how they operate.
When l make comments to my fellow Anglicans about this l get funny looks and it's clear that they think that l must be exaggerating.
It saddens me that most ex JWs seem to see all Christian denominations through the prism of the Watchtower. My experience in Christendom, probably like yours and Mrs Ozzie , bears no relation to the experience of JWs .
So , no , l can't begin to understand how being under the control of the GB affects people emotionally and spiritually.
