wow, you are processing and re-evaluating quite well. Internet helps so much for researching. It is no surprise how the GB/organization are threatened by the Internet. I left in the mid-80s, took me about 10 yrs of revaluating ('75-'85ish, before Internet. A few moves, helped for me to get out of the 'radar' also.
Welcome! I have never for one second regretted leaving that 'unhappifying' life. I look back and realize I did have happy moments/times, but I realized that was due to me, not due to the credit of the organization.
