This article will achieve little. Hardline JWs will continue to be hardline JWs and the growing proportion of more "quietly" disobedient JWs will continue to provide the milk of familial kindness to their disfellowshipped family members.
Expect to see more of these kinds of slyly reasonable articles because the GB knows full well that not all JWs shun family - and certainly fewer still shun them to the ruthless extent advocated in the article. In other words,as irked as the GB must feel, not all JWs are ruthless bastards.
