Plato - dad insists on the matter that when one wants to leave the organization in order to embrace the “worldly” lifestyle - and, by that, he means a pretty moral deprived life for most standards - one will search for mistakes and do the wrong form of questioning.
That's nothing more than indoctrination that was planted in his mind from the cult that controls him. JWs always want to act like those of us that leave do so to lead some morally bankrupt life and it's simply not true. I live a cleaner life than most JWs that I knew that are still in good standing. It's nothing more than an excuse to devalue what someone that leaves has to say. If you can dehumanize a person before even hearing what they have to say then you don't have to be intellectually honest. Your dad is trying to discredit people in the same way that the organization does. It is unfair and they won't have honest conversations because they're incapable of it. What you're dealing with here are "thought stopping techniques" designed to give the JW a way to stop going down a path with someone that could impact their faith. They just discredit the person, and now they don't have to think about it. It is typical cult behavior, even something that abusers do. They tell their victims not to talk to anyone else about what goes on, tell them that other people won't understand, etc.
How you get around that, I'm not sure. It is prejudicial thinking that was implanted through things like the organization calling "apostates" "mentally diseased". The reality is that it is JWs that do the wrong form of questioning in that they do none and aren't allowed to do so, or fear doing so because it would cause them pain if they found out what the truth really was.
I'd be interested in knowing what the "wrong form of questioning" is. Maybe ask him that. What does he mean by the "wrong form of questioning"? Doesn't the Bible say to "make sure of the more important things"? How can one do that wrong? Or does he just mean that people are doing it wrong by looking outside of the JW's written publications? Why would anyone read only one point of view on something and accept it without hearing any other perspective?
How did he get a PhD without asking tough questions, looking over "peer reviewed" papers, etc.? He should know, if he went to college and is educated, that part of learning what is true involves testing things out to see whether they hold water or not. Would he go out on a boat in the middle of a lake that I built simply because I told him that I knew what I was doing? Or would he test it out and put it in the water first and see if water started seeping into the boat or if it was water tight? How can you do that wrong, like he claims?
I don't know, it's hard to do something like help you with specific questioning when there could be so much more around it. And there is more. There is a history of things he was taught and believed that forms the belief that people just leave and question things because they want to act out morally and then somehow they makes them question in the wrong way, which is a bad assertion on both cases.
I'm telling you man, you seem like a good kid and you value your family. Your dad is an elder. The chances that you keep your family and have open and honest discussions about this where you can question things with him are very slim. You have to know this now.
People come on here all the time and fool themselves into thinking that somehow their family will accept them if they question the religion. Everyone thinks that their family will be the one that is different. It rarely is. My wife thought that her family would be okay with us seeing my disfellowshipped brother after 14 years of shunning him. I warned her that they wouldn't. I knew mine wouldn't, and I knew that hers wouldn't either. She listened but did not truly believe me. She was willing to lose them if necessary to do the loving thing and stop psychologically manipulating my brother by shunning him, but she didn't think they'd shun her. Literally the second that they found out her sister texted her, asked if my brother was still disfellowshipped, and once my wife told her that we prayed about it and felt that it was okay to see him and that it was our decision, she called my wife an apostate and said that they could no longer speak. That sister then went and told the entire family, and friends thousands of miles away, spreading the word. The next morning my wife woke up and all of her friends on Facebook were gone. All of those Jehovah's Witnesses shunned her instantly, without any verification, without ever speaking to my wife, without giving her a chance.
You have to go into any of this knowing that you will be shunned. If you aren't shunned, then that's a pleasant surprise and a rarity, but don't go in with any other frame of mind. You're playing with fire here. Most people get burned. You have said already that you can't be okay losing your family. If that's the case, then maybe you shouldn't play with fire. I'm telling you that because I care about you. I am honestly not sure what game your father is playing with you but it is very dangerous to you. If you play a game where you are honest and are punished for being honest, then you are playing a game that is rigged. Maybe you shouldn't play that game. Your dad may be deluded and thinks that he can play the game with you because he's so sure that he has "The Truth" that you can't possibly see things any other way. He has no idea what he's doing if that's the case. Everyone will lose in this game because the JW cult rigged it.
