But, your parents are not to blame, and have no conception of the anger you hold inside. They, like many of us, were drawn in by thoughts of a loving God making this earth a cleansed paradise. They want wickedness such as you observed to end, and for all people to be loving and peaceful.
Thanks for the comments Quandry. This is something that makes it all the harder. I know that the individuals within the org are generally nice and good people drawn in by the illusion of a loving society. If my parents were fully concious of how evil it really was and still went along with it, I would have no problem giving an ultimatum along the lines of "choose your family or the religion", and I'd happily walk away without a second thought if they chose the WTS. But they don't realise, and are not conciously practicing the evil policies of the borg.
The society does paint a very rosy picture of happy smiling "united" families, sat in a paradise, and it cleverly gives the impression that they are family orientated. But the more I see on this forum, the more I realise the family is not in the least bit important to them. This forum is filled with people who have had their family ripped to pieces. I think the post by mouthy http://www.jehovahs-witness.com/6/134305/1.ashx sums this up completely. Very sad.
I think this anti-family aproach may be my best hope as family is very important, especially to my mother. All my brothers and sisters have left the org, and none of the extended family are or ever were in, so my parents are the only ones left. Maybe showing how the society (run by old men that have never had families) are so against the family, to the point that you should disown a relative for being raped, is the way to convince them that this isn't quite as the happy images would suggest.
The congnitive dissonance link is great, thanks jgnat. It's amazing how easily a mind can be manipulated.
