So in sociology we divide organizations up into three categories or types, you got utilitarian, voluntary, and coercive. Utilitarian means people join to accomplish some purpose like selling food or making furniture, voluntary means they join up just for fun or to hang out with people like the Freemasons or a lot of churches, and coercive means they don't really want to be there but they gotta because someone will punish them if they leave, so labor camps, armies, or prisons.
In a paper I wrote for a class a while back I argued that Jehovah's Witnesses should be seen as a coercive organization. Yeah, people join up and they do leave, nobody beats you up if you stop attending or preaching, nobody imprisons you, shoots your dog, kills your kids that kind of thing, and nobody makes you join up either. But that doesn't change the fact that the Governing Body and other elites tell Jehovah's Witnesses that if they leave Jesus will kill them at Armageddon. In my mind that's the essence of coercive. In fact, what could be more coercive? Just last year Kenneth Flodin got on JW Broadcasting, compared a wine glass to lax Witnesses, and then smashed it on the floor and gave the camera a long dark stare. Now Tony Morris tells audience he's going to help Jesus kill unbelievers at Armageddon, and the Watchtower prints the same thing, along with colorful illustrations of the carnage, the kind of suck stuff they showed kids in the 60s and 70s, I mean, can you make more blatant threats?
Jehovah's Witnesses don't qualify as a voluntary organization, period. There's no real difference between telling someone your friends (Jesus and his angels) will kill them soon and you'll kill them soon, and besides... the Governing Body already said they would kill the unspecified 'wicked' any day now on multiple occasions.
