I became one.
I started off as a poster child for the JW's. I was from a divided home, and I reached out early. I started going door-to-door giving presentations by myself at age 4. I joined the ministry school at the age of six. I even got baptized at 12, and was immediately tapped to conduct a book study at 12 (this was before the elder arrangement).
But there were things that bothered me. My father smoked like a fiend, and my suits were in the same closet as his. I was interrogated regularly about whether I smoked, because my garments smelled like smoke. At the age of 9, I had an encounter with the Congregation overseer about one of his sick accusations. I had a friend in the congregation that was morbidly obese. This was an old Kingdom Hall, an old house that was converted. They stuffed those gross little wooden folding chairs everywhere (remember them from old circuit assemblies) and we sat next each other in one of the alcoves by the stairs. After the meeting, this brother accused us of sitting too close together, and that we may be homosexual. We were freaking 9 years old!
After more things went down, my respect for congregational authority waned. I was sexually abused by an elder, and I have a period of 2 years of my life that the memories are totally repressed to this day. I became a bad ass as a teen, and rebelled, but never at that point that they could take congregational action. They tried, but could never make anything stick.
So, yes, I was a bad witness.
