Official welcome to you, a long-time reader, first-time poster.
You have checked out of the Hotel-Jehovah's-Witnesses but you can never truly leave because of your family ties. I would like to make an excuse for your father, but I cannot. I don't know him at all and whether he is just another victim of the cult or a willing "flaming ashpile" (that is what you meant, isn't it?).
He just might be another one who could say "We are all just prisoners here, of our own device"
I hope you feel welcome to vent here and that some help is found. See you around the water cooler.
