Some bring their "loony-ness" with them when they join, others learn it. I've watched my mom change over the years. She's not a loony but over the years she's got some pretty strange ideas. Most came from a know-it-all neighbor we had when I was growing up. As a kid, junk food was almost non-existent. Maybe once every couple of months I could have a Coke. Sugar was a big no-no because "eating too much sugar gives you sugar diabetes". Yep. That's the term. "Sugar diabetes". And mom learned that eating too much sugar caused it. Want to know why I don't have a microwave? Because mom didn't want one when I was growing up. The radiation could kill you or at least make you very sick. At least she never linked microwaves with sugar diabetes, but it wouldn't have suprised me if she had.
Think about it. It's a closed society. Almost all learning beyond the most basic education and job skills is discouraged. The gaps in knowledge therefore are all too often filled with passed-on misinformation. Add the belief that an army of evil spirits is always watching and waiting for the chance to "get them" and I'm personally suprised there haven't been stonings and burnings in their ranks.
For instance. I remember one brother in our congregation whose wife got cancer. He wanted her to beat that cancer, not merely be treated by the local hillbilly doctors. He researched her cancer (sorry, can't remember specifics) and ended up taking her out of the country for some kind of experimental treatment. He came back to face judicial action because of it.
Thankfully the internet is changing all that. The Empire can demonize it all they want, but it's here to stay and it's not going to stay out of Witness homes. It isn't staying out of Witness homes. They don't even need a $1000 computer to access the net. All they need is a $100, even cheaper if bought used, box that connects to their TV and what Witness home doesn't have a TV? They can villify it all they want but more and more Witnesses will accept the information superhighway into their homes and lives.
What I'm trying to say is that there's gonna be less and less loonies in the Empire. Just give 'em time.
Mike.
