why the reliance on pointing out hypocrites to prove points?
Well, for one thing, this is what the WTS and JWs do to "prove" that all other religions cannot be the One True Religion™. Why should they expect to be above similar scrutiny? "With what judgment you are judging, you will be judged; and with the measure that you are measuring out, you will have measured out to you" is what Jesus said right after he commanded his disciples to stop judging one another. (Matthew 7)
Have you taken any ethics courses in med school yet? What would be your ethical responsibility if you found out that the Chief of Surgery where you worked was involved in corrupt practices - like a conflict of interest for example - that were endangering the lives of patients? Wouldn't you feel compelled to do something to spare innocent lives from harm?
Most of us here have been compelled by our consciences and our sense of ethics to expose "wrongdoing" (as the WTS would call it when applied to a follower) committed by the WTS. Do you realize that a JW can be disfellowshipped/disassociated for joining an organization like the YMCA even if it is only to use the swimming pool? Yet the WTS affiliated itself with the UN (and remains affiliated with the UN), an organization that the WTS itself has identified as the scarlet coloured wild beast of Revelation that commits spiritual fornication with "Babylon the Great" (the harlot who rides the beast), whom the WTS has identified as the World Empire of False Religion™. They require a level of purity of their followers that they are not even willing to fulfill themselves. In their publications they state that someone who joins an organization whose purposes are in opposition to God's Heavenly Government™ has voluntarily disassociated from the JWs on the grounds of "spiritual fornication" and is subject to shunning by friends and family, while at the same time the WTS does exactly the same thing with impunity. There are no checks and balances of accountability - and that makes the organization potentially quite dangerous.
That's just the beginning.
You say you have a psych background - have you ever studied Lifton's work on thought reform and totalism? JWs fit all eight criteria that Lifton identified in groups who employ unethical forms of thought reform/mind control. Why don't you check it out, and come back to discuss it with us?
Welcome to JWD!
