People who join aren't fully exposed to the WT, though. I think Leaving used that adjective "fully" intentionally. You don't become fully exposed to the Watchtower for years, sometimes decades after joining; sometimes never. When you learn the truth about the Borg, there are different ways to react, and the leadership has primed the believers with several of them, including "wait on Jehovah" "we're imperfect but it's God's organization" "where else shall we go to?"
But a critical thinker is eventually going to think his/her way through that stuff because it doesn't pass logical muster when held up against the flaws, sins, and crimes of the organization.
One important key, then, is to break the Information Control and make the truth about the Borg available as much as possible.
(btw, thanks for the props, LWT)
I'd like to comment on this, as well:
Facebook and other social networking sites do play a role in the breakdown of some marriages. That's not something that is justed touted by WT. Lots of single and married witnesses' (and non-witnesses of course) lives are playing out over these sites. It's not a cause per se, but it definitely is a factor many cases.
How do you know this is true? Unless you are very active on the FB pages of many JW individuals and groups you are just trusting hearsay.
Lots of things contribute to marriage breakups. Claiming that a particular type of Internet interaction is a cause of many marriage breakups is an extraordinary claim that demands extraordinary evidence. To date I have seen none. I don't doubt that there have been JWs who met others online and left their spouse for them, or had an affair with them. But "many"? And is Facebook really a causal factor?
