If the Bible sez that shunning applies to "anyone called a brother" who engages in serious sin,
then logically, if a person made clear to everyone - congregation, neighbors and community - that he is
not one of JW's, no shunning would apply - over and above any 'worldly person'.
Likewise, it would not apply to any DF'd person either - if they made clear they are no longer a JW in any way.
Of course, such logic cannot be grasped by the Watchtower - who would voluntarily submit to their dominance
if they allowed such things? Coercion is all they know - people have to be forced into 'returning'.
