It seems to be human nature to ask the question of "why", and too many of us in the process attempt to put everyone in the same box after answering the question. Is it possible to have a childhood trauma lead you down a particular path to somewhere...yes. We do not live in a one size fits all world, so I assume the question is a curiousity to see if there are many of us out there that would fit the bill.
In my case, I would consider it a childhood trauma that lead me down this CD path. A common punishment from 4 years upward was being dressed in various forms of girls clothes as a punishment. Was this to emasculate me, no, I don't think so, but to shame me, yes. It seems so ironic that my Dad wanted a man's man for a son and didn't get one, could it have been a result of the punishments, who knows. Did this shape my personality into what it is today, probably, but one will never know for sure, and that only leads to more questions.
We are who we are and if one person wants to justify their actions by saying it was a trauma, does it make it any different than the person who says it is in their genetic make up. If your justification helps you sleep at night, then it at least gave you a good nights sleep. We all have to learn to deal with it and get on with life. Through my time on this site I have bounced around in my thinking about who/why I am and I suspect that others have also. I questioned my thoughts about how far this will go, it is kind of like watching a pendulum swing from one extreme to the other. Through these swings I have personally come to the point of finding my happy medium, and I hope others do to. Another question is has the pendulum stopped moving yet?
I think that these type of questions are a good thing, because it gets me thinking and helps me focus on helping myself become a better person, and helping others to become all we can be inspite who we are.
