The NGO thing was one of the major contributors to making me wake up and question the WTS. When I discussed this with the circuit overseer he basically agreed that he wasn't happy about it but it was something he had overcome...then he gave me a whole load of copies of bulls**t letters that were released to the congregations to explain it all away...they were such a load of crap...and yet many buy into the excuses...some people just don't want to see it because its too challenging I suppose.
Here is a link to one of the older posts on here that sheds a bit of light on how the NGO's are answerable to the UN.

I recommend having a look at a few of the other old posts about it...some interesting info.
