Way back in 1980 or so, there was a movie, made in New Zealand, where some physics experiment goes wrong and causes every living thing to disappear, except for three people. The first guy the movie follows is totally alone, and he revels in it for a while, moves into a luxury house, and crossdresses. I cannot remember the name of the movie, but that image will stay with me forever. I wanted the apocalypse to happen so I could go around dressed like a girl with no consequences to worry about.
So the question is, if the apocalypse happened and you were totally alone, would you present female? (Assuming you were assigned male at birth).
To me, the question is a resounding yes -- I want to look female even if no one is around. The motivation to do it is purely internal.
Conversely, what is your motivation for presenting male? Is it because you feel that is what you have to do in order to get by in society, and get other people to perceive you the way you want? If the motivation is purely external, then at least by my definition, you are transgender.
In an ideal world we present as our chosen gender for no one but ourselves. At home, behind the privacy wall, I present female as much as I can every chance I get. Out in the world, I present male because I have to. That is what it takes to keep my career and business on track and my wife happy.
I am transgender.
I wish it were not that way. Leelah Alcorn challenged us to "fix society."
I am trying, one person and one encounter at a time.
