Onthewayout: JW's have 8 million or so members, but they haven't (yet) told the members to drink the Kool-Aid like they did at Jonestown.
The WTS has their members sign no blood cards instead.
The number of JWs who have quietly, and some not so quietly, committed suicide for the blood cult far outweighs the numbers who gave up their lives dramatically in cults like Heaven's Gate and Jonestown.
The WTS is more subtle than "those other cults". And far more effective. They have been getting their members to commit suicide for 70 years now.
