I read a comment somewhere that having a beard ( before such was allowed) was never a disfellowshippable offence. But does that mean that no-one who grew a beard was ever eventually disfellowshipped?
Growing a beard when such was frowned upon would surely attract the attention of those with nothing better to do, and possibly lead to sniffing around to try and find things that the "disobedient" one was up to. And I imagine that such "weak ones" were subject to "soft shunning" ; not officially shunned, but avoided anyway.
And it wouldn't be just be beards. It'd be all those areas that aren't rules, but you know for damned sure that they are rules. For example, LongHairGal suggests that her refusal to quit her job and further refusal to pioneer lowered her "worth" in the congregation. There'd be more examples. Women who refused to wear skirts in field service in Winter and so on.
So when is not disfellowshippable actually shunnable?
