The closed community and high control, on the up side, did provide a ready made social structure, The tight community provided a bit of safety, not sure that is the right word, and comfort. It was really nice when traveling to meet up with or stay with those in the ready made community. Some of the best times in my life were meeting up and staying with other JW's around the world.
That being said, I know it wasn't good for millions of others. If you didn't "fit", it is miserable, painful. And it's really a cruel community, now that I'm out.
I will say, those exJW's I've had the pleasure of meeting up with bring that same sense of community along with freedom of thought and acceptance. That is the best ever.
