Wing Commander, I rather err on the side of thinking their figures for active J.W's may be not too far off. But they base the figures on slips of paper, "Reports" that are mainly fiction, and therefor not from full-on believers.
I have not spoken to that many J.W's in the last year say, but the handful I did talk to ALL expressed doubts of a serious nature. Lets be generous, and give 'em 8,000,000 worldwide, but how many of those REALLY believe ?
The Daily Fail and Independent picking up on all this will cause more to doubt !
