What makes me smile about these type of visits is the real lack of imagination on the part of the elders. They spend the time trying counsel the sister on fictional events as if she could only write about a relationship between two people if the conduct was as two Witnesses would be expected to maintain.
If they really felt the need to shepherd the sister then the more logical tack is to talk about how some may find the content unacceptable and the risk of stumbling. They should also never have avoided the Matt 18 issue. It's got to be easiest thing in the world to suggest to someone that they go and speak to someone they are complaining about. At least then they could have said they were sending any who felt offended to go and speak to the sister directly whilst also being able to say to any complainers that the matter has been handled. It helps quash the rumours, stops elders wasting their time and reduces bad feeling.
At the end of the day, if the book was out there then it's never going to be pulled off the shelves. The elders must know there is no real JC action so what's the point of coming out with lines about what is acceptable or unacceptable. My guess is that the sum total of 0 people would, if advised by the elders, actually go and apply Matt 18 even if the elders then said that if they didn't they would not be giving the "offender" the opportunity to apply Matt 5.
I've seen it time and time again where lack of thought and knee jerk reactions mean elders end up looking stupid and waste endless amounts of time. The elders could save themselves so much hassle if they just told people to apply Matt 18.
