It is really sad how the WT has produced such an apostate view of the subject of being born in the spirit. This is a basic part of the new covenant and what, as far as living goes, makes the new covenant superior to the old.
I think what many of the commentors here are seeing in their experiences with "anointed" that they have known is the logical result of the WT's warped teaching and the effectiveness of their indoctrination methods. What I mean by that is this:
The WT has done an excellent job of indoctrinating their apostate view of the subject of anointing into the R&F JWs. If the Society had their way, few, if any, would think of themselves as anointed, except their leadership, and maybe the odd, zealous older person here and there. The Society would be quite satisfied if this were the case, as it would fit their power structure and prophetic viewpoint quite nicely.
As many here have pointed out, via their experience, many of those who claim to be "anointed" are somewhat 'strange' (for lack of a better word). When you think about it, that makes perfect sense. Most of the JWs that are of normal thinking ability will tend to 'get the point.' That is, they 'get the point' that the WT wants them to get concerning the anointed, namely, that they are not one of 'them.'
It is the ones who are somewhat 'different' in their thinking abilities who don't get the WT's point. There are always people like that in every walk of life that somehow don't react correctly to "do not enter," or "turn left" (and they turn right). They tend to somehow miss what is obvious to the majority.
And thus, among those in the KH that partake, there is a large percentage of the few that don't fit in with the majority. If the WT taught about the subject correctly, then, partakers would represent a sampling from all sorts of people, including the strange ones mentioned in the comments above. But since the Society doesn't teach the subject correctly, you only (in large part), see the abnormal ones, the ones who fail to go along with the program, so to speak.
The real object of derision in this topic should be the WT. The comments above are the end result of their apostasy from Christian teaching.
