Sorry I haven't read all the comments yet, and hopefully I'm not repeating anyone else, but growing up as a JW and then in my early 20's I did a count of all the "kids" I grew up with who were still in "the Truth" and I was still very much active as a JW at the time....anyway, out of the 20 something kids I grew up with, it was just me and one other person who were still in "the Truth," LOL I guess now it's just that one person since I have recently "left"
I also know in my late teens my family and I moved to a different cong. and out of about 10 around my age group, they ALL are no longer JW's.
I'd say it might just depend on your hall, but I do know a lot of people who leave once they are in their teens. I recently reconnected with one of those I grew up with who left when she was 16 and she told me "I knew it was a cult even at 16, that's why I left and did what I did to get away from it" (She had a problem with drugs in her younger years, that is what she was referring to). With anything it's always the unknown and the it depends as to why kids leave or not.
I'm hoping my nephew when he hits his teen years realizes what really is behind WT. It's funny because he has always been super pro-WT and wanted to get baptized at age 8 and he even went through the questions and the elders said no (thank God), and it's been two years now and he hasn't eve talked about it at all. I'm hoping he won't!
Great post!
