Confrontation is not a good idea always. Not giving your heart to things you do not approve is a sweet rebellion with no possibility of ever being noticed/punished.
Isw61,
I totally understand that you have to keep up pretenses for your loved ones. I know other witnesses who are in the same unenviable position that you are in. If you can stomach the mental torture, then stay in and try to change things from the inside. Don't just secretly disapprove of their failings. Inaction from those still in like you will only prolong the injustice and pain that is being inflicted on your fellow brothers.
But be warned, sooner or later reality will catch up with you. You can't have your cake and eat it, too. It will get ripped out from your hands because the whole organization is trained top to bottom to spy on each other.
