Lots of variations between the extreme of total stealth and totally out. I doubt many do either. From my own experience I truly appreciate the good fortune (and hard work) that gave me the ability to pass. Its a privilege as it gives you privacy and choice. I also know, clearly, that some will never be able to pass.
The proud part is different though. I have been thinking, what exactly does that mean? That you are proud of being trans? I dont feel that way at all, it seems to me more like a disabling condition, some do better than others but no matter what we never have fully functional bodies. Someone talked about people in wheelchairs, to me being trans is a little like that. Some go on to be para olympic athletes. Still disabled, but clearly they do not allow their disability to define them and move on and make the most they possibly can out of their life. Others slide into depression and dont do well at all. Im not judging anyone at all, its just that some people cope with things better than others do. And of course, no one knows what other issues someone might have that contribute to things.
So I feel proud, not because I am trans, but because I dont allow it to define me. I worked really hard to change as fully and convincingly and correctly as my ability permitted. I never forget that I had some good fortune to help me and I always take the oppourtunity to help others as a way of giving something back. I feel proud of that, I feel proud of myself and who I am and what I have done. But so far as being trans goes not really. Its just a thing, maybe an obstacle I had to overcome.
But others might feel different. And thats okay, just so long as they dont expect me to think they are better or more authentic or stronger.
