Ahhh......but the 'out' that I always hear is exactly what they've put in the article "it instructs those who love God to obey God as ruler rather than men"..
All JW's believe that the GB are not men but God. So they will obey first the GB in what they teach above what their family might wish.
Second out is their statement "at times loyalty to God (WTS) may result in your making a decision that is unpopular with some family members". Although you may read the message of the article as not having to make a choice - the intent of the article is to simply reinforce decisions made by family members to shun and cut off their kin. In other words, it may be unpopular to shun your child, but your loyalty is first to God (WTS) and thus it is not a choice you have made - it is your loyalty to God (WTS) and that makes it okay. sammieswife.
