I don't think you need to be an extremist or a person who "naturally pushes other people away" to become a JW.
No, and that's the point. Of course, I'm not saying EVERYBODY who is a JW is an extremist, just that there's likely an over-representation of those with bonding issues (AKA attachment disorders), compared to the general population.
(And by stretching my words, you're showing a tendency for jumping to extremes yourself: kinda ironic, no?).
The thing is, JWs DO read the message of Jesus' family values pretty accurately to what the Bible actually says, and they don't even try to bury it, or deny it: for them, the scriptures of Jesus saying he didn't come to bring families together but to tear them apart, etc, becomes a self-fulfilling prophecy, even a badge of honor so they can say, "Well, Jesus warned about this kind of thing and we're paying the price", so they can use it as an opportunity to display their infamous persecution complexes.
It's not all that hard to understand that EVERY GROUP has core beliefs and values; prospective members are going to be attracted to such groups that share their pre-existing principles: that's why ultra-conservative Tea Party types don't recruit for prospective members in big-city slums, why you don't see clear-cut loggers joining the Sierra Club, skin-heads don't join NAACP, etc.
Similarly, there's a profile and mind-set of a typical or average JW who's attracted to the message sold by the WTBTS, and the WTBTS fully-well knows the psychological profile of their target audience.
Flip-side is there's MANY MORE people who COMPLETELY don't fit their profile, and they wouldn't become a JW, even if you held a gun to their heads. It's a rather narrow set of beliefs, and hence why there's only 7 million members Worldwide (out of 7 BILLION).
And of course, there's many different reasons for shunning: sometimes out of self-preservation, other times on religious grounds. In a sense, they are doing it for BOTH reasons: they often truly believe that their surviving A depends on their willingness to shun, and I can't believe there's not some measure of self-awareness of the selfishness of their actions, causing some guilt (AKA 'survivor guilt', except anticipatory). Is it selfish? Sure.
But is it any more selfish than us shunning them, based on OUR own need for self-preservation and maintaining a sense of our emotional and mental well-being?
