I didn't mind most of those restrictions of being a JW. I still do not "celebrate" holidays although I acknowledge the birthdays or our kids, grandkids, and close friends. I still have conservative grooming and values.
I left because I came to realize there really was no divine direction at any level of the Organization. Yes, I had really believed that there was. I really thought there was some kinda voodoo "spirit direction" there. I was convinced I had experienced it -- had seen evidence of it. Now I call all that coincidence, because I am ever more convinced that there is NO supernatural force or being guiding anything or anyone at any level there. I was absolutely crushed upon coming to that realization. ALL that I had believed in came crashing down around me.
I now believe it is "mostly" good men/people who are trying to do their best at understanding the scriptures and applying it personally and conscientiously , but unfortunately some also going to the extreme in forcing their opinion or understanding of it on others conscience. There really is no such thing as a person's Bible trained conscience. There is the GB demanded conscience. If your conscience does not agree with their direction 100%, you're going to be in trouble there and likely forcibly removed from the group.
