For me, it was primarily the falseness of their 607 date and all of the ridiculous things they had taught and believed in the past. There was no doubt that God was not using this group in any way.
For the most part, I was treated rather well in the organization but I was aware that many were not and that double standards existed for those who were of the 'in' crowd and for those who were not. Hypocrisy and lack of love and the constant complaining in private discussions always wore on me.
That feeling that 'something is very wrong' was finally satisfied when I could be honest and say things were wrong because the religion and it's leadership was wrong. I was also disillusioned with the way their teachings had become watered down, particularly the generation change in 1995.
The organization held out nothing that interested me and 'privilege and position' they offered had no motivating effect on me. Being a young person, I knew they had lost a complete generation and how well we could keep things hidden from them. In my conversations with them, I realized most just had no clue even though we'd frequently go to parties of 500 or more Witnesses in the area, they were just that dense.
Field service was a pathetic ritual, and because the message had become weak and vague I found myself at loss for what I was really teaching. The amount of time spent on this imaginary ministry and the promoting of it seemed unwisely at the expense of a much needed internal ministry. It hardly made any sense that we'd spend endless hours searching for the odd new recruit when the young people were leaving in droves out the back door. The focus was all wrong and nothing seemed to be in the works to effectively address this.
Many elders (and their wives) and COs and bethelites or otherwise people who had some 'inside scoup' would admit many concerns in private honest conversations. All of these things added up to paint a picture of an organization in crisis while publicly presenting itself to be at the top of its game.
Everyone was wearing out and getting tired, and so was I. I had to leave and salvage my life. No regrets.
