Thinker,
You won't find the demon theory in print, it was part of the oral tradition in the witness culture. I'll give you an example. My wife's mother and father retired to Arizona from Ohio. They bought a piece of furniture in Mexico and later my mother-in-law concluded that it was demonized and got rid of it (Perhaps Mexicans have more demons than we do.) Later, my wife's folks paid for my youngest daught to visit; their purpose was to convert her. She brought along her diary against my wife's advice. I think her diary had some explicit fantasies in it. The devious grandmother went through my daughter's things and read the diary, and concluded that my very sweet, nice daughter was demon possessed. I often thought that this theory was especially peculiar. If a demon wanted to hang around wouldn't it just flit from one thing to another? Why would it leave because the sofa left? If I was a demon, I wouldn't live in a smelly old sofa, I would be sitting next to you watching television and I would channel surf when you left the room. JW's think theories are bad but they sure had one here, and it was a strange one.
Path,
I met a young witness male who was a senior in a 5 year college engineering program. so he was an exception to the rule, although, as you point out, there are local variations in what is acceptable.
Dress code: A couple years ago there was a convention in my city. I dropped in, but did not fit in since I had a beard..I would describe the general style of dress at the convention as 1950's Ozzie and Harriet.
Does the severity of treatment towards those who have left vary over time? My sister didn't talk to me for fifteen years; now she does. Is she breaking the rules?
Have the funeral services improved any? They used to spend a lot of time on doctrine and almost no time talking about the deceased. They did not realize how offensive this was to non-JW friends and relatives.
