I did several times at different congregations, then I finally accepted hoping to make a difference. I have to admit I was probably the favorite in the congregation, wasn't quick to judge, and the friends found me easy to talk to, especially among the younger ones.
My presiding overseer hated me because I wasn't a "Yes" man who kissed his butt at every opportunity. But at the same time he respected me because he knew I never held back. I spoke my mind without any reservation.
We use to go at it tooth and nail at elder's meetings. One time he actually charged at me, took 3 elders to hold him back.
In the end, I had enough, and I handed in my resignation, I had confided to quite a few friends, telling them I couldn't do it any more and they begged me to stay, but they understood. They announced it during the service meeting as if I had been removed, and not stepped down, but everyone there knew I stepped down.
I kicked the bookstudy and field service group out of my home, and told the elders the only thing I would participate in was field service, which I enjoyed.
The following Sunday just before the Watchtower study was to begin, an elder tapped me on the shoulder and motioned me to the back, when I got there He extended the microphone to me and I immediately put up my hands and told him "I don't do that anymore", he had a smirk on his face, I went back to my seat. I lasted a few months. Then walked out and never went back, that was some 25 years ago.
