I think I was a certain "type" when I accepted "the Truth." I can say this because when I grew out of those habits and views I was able to re-evaluate myself and compare myself to why I felt like I didn't belong and had to get myself out from the Witnesses.
Me, I thought that there had to be one "truth" or a "right way" to life. I was determined to find it.
I was also the type of person that believed myself to be humble, but secretly I enjoined being the center of attention and having answers and filled with "facts" (what I now call "factoids") that would impress others.
I also had the habit of viewing myself and my worldview as the right one, no matter what it was.
And I rarely viewed myself as possibly mistaken. My path was the right one because I had done the research myself and now knew better. Those who did not take this path were the ones who were mistaken. Life was a game of constant compartmentalization.
That was me before being a JW. I fit in nicely upon joining and got my pats on the back and enjoyed how proud I could be in now finding "the one true religion." But I was just a teenager then.
Along come my 20s and I could see how my idealism just wasn't realism. How could I be the judge of myself and my choices? Even when I was greatly mistaken in the past, I could never really tell. It feels just as right to be wrong as it does to be right, and we often pick and choose the "facts" we wish to believe in.
When I grew out of that I stuck out like a sore thumb in the Kingdom Hall. Along came the elder visits, asking me if I was giving in to "independent thinking" and having doubts about "this being the truth and the one true organization." I was no longer walking like a duck or quacking like a duck, so the other ducks could see I was just not a duck. But I once was, and like the ugly duckling of fairy tales I grew up to be something quite different and unexpected.
I can't say this applies to everyone, but as I mentioned in a previous post, I didn't let go out this pattern right away. I quickly embraced an anti-religious and very militant atheist ideology. Now atheism was "the Truth," and all people who embraced anything but were the hated, the unenlightened masses. My new gospel had to be preached, and I did it every time someone mentioned religion or any view that did not agree with mine.
Both a family of atheists and academics from the universities that graced me with their patience helped me see there was more than doctrine at error. It was a way of thinking, a personality trait ( or a series of them in me) that was flawed.
I think a lot of JWs are like that. I met a sister who had left the Church of Christ, believing it was the truth until she studied with the Witnesses and learned they had it. My best friend had once been a Mormon, believing he had the truth until he studied the Live Forever book and realized the Witnesses had it.
Atheists who had never had a religion or grown up in one never felt the need I had to "spread" their message around as truth. Coming out of the Watchtower I learned that people don't choose religions because they necessarily want to be right or have the "only truth." I was looking for a club that would keep my illusion of being in the right alive, and pat me on the back for my compartmentalizing. And if one group didn't necessarily do that, I would alter their set of convictions to fit my needs.
