I think, there's a structure:
1) Nuts
2) Low Level Believers (think it's the truth but don't study anything)
3) Believers (think it's the truth and study only jw-books)
4) Hardcore-JWs (don't think and study hard)
And here is the problem with the teaching:
1) You avoid them, because they nuts.
2) You look for them too dub-style.
3) You look too much like 2) or 4)
4) You only access this area if you be a pioneer or so.
At the end, it's all based on fear. If you low-level you be connected, if you a hi one also. Everything in between mostly screwed.
