I've known three. Two genuine Christian men. One a complete front loop who ended up getting the book thrown at him during a custody hearing. The judge was not happy with his brand of raving lunacy. He represented himself. He was thought to have been a replacement for one of the annointed who fell away.
The oldest of the three was a colporter back in the day. He treated his non-anointed wife with great love and respect, even stating that the society needed to show more respect toward women. I regularly sat in on a study he conducted with a woman in his later life-- not the norm, I know. She did get baptized, but was later disfellowshipped for wickedness. It seems she had over 12 (I think 13) lifesaving blood transfusions and was not repentant. She would not sign a letter stating it was a moment of weakness and that she wouldn't do it again. One day the crows were particularly loud and annoying and disrupted their study. He believed Satan sent them to interfere. He died with late-stage dementia. He was well-loved.
I didn't now the third well, but worked with him in the ministry. He was a true believer and a company man through and through.
