Papua New Guinea (a country in which I recently lived for a total of eight years, and thus had ample opportunity in which to observe 1. what is local custom, and 2. what the WTS stand was.)
according to the WT$ local customs are to be ignored by anyone who is a "christian", as quoted in the 09/15/2013 WT:
But does this mean that as long as long as there is no clearly stated law from God, we can just follow the ways and standards that we are brought up with and that are common in our area? There are at least two important reason why that is not so for Christians.
Emphasis mine. It has nothing to do with customs, or what people perceive that jw's preach at. It is all about CONTROL. How many hoops can we make you jump through? How high can we get you to jump? How much of what makes an individual unique can we stifle in the interest of uniformity and sameness?
