As a young man I knew several. My mother always wanted me associating with the creme of the crop. But because of my youth I am sure I didn't get the real person. A couple I knew and felt were good people in and out.
My first experience witht he nuttier side of these people is when in a hall I was visiting a woman gave me strict counsel to break up with my black girlfriend so that our being out in the ministry together would not detract from the message. that she was anointed and I should listen to her.
My girlfriend was fine, and a great person (still a JW), so I passed on her racist advise. But yeah.....that was an eye opener.
