Demonizing or villifying anyone who dares to disagree with you is one of the 8 tools that cults use to brainwash.
My parents are still practicing JWs although somewhat inactive, mainly due to age and health. But, I don't discuss my difference with them. They really want that New Order they've worked for most of their adult lives and I haven't the heart to wrest it from them with arguments they wouldn't believe anyway.
I just...feel very sorry for the rank and file. They would just be horrified and run at hearing this, it wouldn't do much good at all.
Realizing that this wasn't for me took me a very long time and it was very gradual. I had to have each piece of it wrested from me with a fight, and it's still a fight, because I still long for the "good stuff" sometimes. The feeling of belonging is the main thing for some people, even if they doubt a teaching or idea, they quickly put it out of their minds because it would endanger that.
