Exiting the JWs involves a kind of grieving process. According to Elisabeth Kübler-Ross along with grief comes a cycle of various behaviours or coping mechanisms which help a person to deal with their grief.
Denial - "oh no, it just can't be true!"
Anger - "holy crap, it is true, how could they do this to us?"
Bargaining - "if I can fix what's wrong without upsetting anyone, then I'll stay"
Depression - "oh what's the use in trying, it's just me against a huge organization"
Acceptance - "the organization isn't going to change, so I have to do something to help myself"
Yes, many of us experience anger when we learn about the reality of the organization known as Jehovah's Witnesses and the Watchtower Society. Rightfully so. The lies and deception, the scandals, the mental and emotional abuse, all those are very good reasons to feel the way we do: ANGRY.
Anger is a part of the healing process, just as much as the initial shock and disbelief. It's also as much a part of the healing process as acceptance of what we've come to know.
The fact is, this forum is a very therapeutic venue for those of us who can share our experiences as JWs. We all know what it's like to "be there". For someone who hasn't "been there" or isn't willing to acknowledge the pain that we have felt, there's no way to convey what we've been through so that understanding can be achieved. Sometimes these things require 'walking a few miles in another person's shoes'.
It doesn't matter that you perceive 'bitterness' here. As someone else expressed, for what the Watchtower Society has done - in the Name of God - one would have to be completely ignorant or a fool to not feel anger, righteous indignation, and yes bitterness. Many people lost half their life. Some of us lost our childhood. Most, if not all, of us have lost family relationships and long time friends. That's reason enough to feel those things. For someone to criticise those valid feelings, they have no right to do so.
This is "our" grieving process, our healing. Nobody has the right to try to take it away from us.
