I have a hard time seeing someone with their actual picture and job with their posts and who has so frankly and personally discussed issues here as inhibited in the first place, though granted you are likely very different in Real Life.
I am about as far away from being an "activist" by nature as it's possible to be. Marigold is an outgoing extrovert in comparison. I left my comfort zone behind a long, long time ago.
But...
Someone has to do this. Somehow, by sheer luck as far as I can tell, I've been put in an immensely privileged position compared with all other Trans and Intersex people I know. I have talents from an unusual neurology. I got a "get out of Hell free" card when I was too terrified to transition volitionally. I have kept job, family, friends, and marriage. I've had a very privileged access to education, paid for by parents who beggared themselves to give it to me. I'm frugal to a fault, so even with a limited income, I have more disposable wealth than many.
"From those to whom much is given, much is expected". Not so much "survivor's guilt" as being in a unique position to make a difference. All I have to do... is go against my every wish for quiet, private obscurity. If I'm going to do that, may as well go all the way, it's no more uncomfortable appearing on national TV as going out the front door. Or being a very straight-laced conventional woman addressing a crowd of exceedingly queer people on the front lawns of parliament house.

You really, really have to have a sense of humour about this. The Universe was having its little joke with me. Also blowing away some of my conservatism. They accepted my own difference after all.
The thing is... biologically, all of them are comparatively humdrum compared to my own unusual metabolism. XXY, X/XY, all common stuff. I'm the weirdest of the lot, biologially. Makes my own conventionality and aversion to anything unusual look rather silly, doesn't it? *SIGH* The Universe is an Iron.
