WOW! Had a discussion about these pins and things few months back with my wife. I pointed out to her how idolatrous this was. Obviously she attempted to justify it saying that this was just some brothers who probably don't realize what they are doing. I told her that might be, but where are the elders? Told her that may be but that if in a few months those things were not addressed, then I had to assume they were seen as approved and that anyone who would see that out on the streets would condemn us for idolatry. Not only it has not been addressed by the elders, this gal is wearing it in front of the very man with the most strict views.
This pin is WTS approved.
David Splane and the GB Helper who were at one of the Atlanta International Conventions both wore JW dot ORG badges on the stage giving their talks. That convention was also tied into the huge Houston RC that had over 60,000 in attendance. If that's not approval, I don't know what is.
