No, I don't feel "dirty." I have been out for 36 years, so most of my issues are resolved. Life is a learning experience, and I feel I had to do the "Watchtower thing" to learn what I did. People tried to stop me, but I wouldn't listen because the brainwashing took so well. While I wish I had spent those years more productively, I know it could have been worse. After all, there are worse cults.
What I learned inside the cult was not all useless. As a teenager, when I first began "publishing," being a JW actually opened up my world and possibilities for travel and meeting other people. The experience started out very positive and went downhill after a time.
I am grateful that I escaped relatively unscathed and young enough to start over.
