I don't know whether religious people merely lean on their religion to provide excuses for that which they don't like, or are really guided by their belief system.
My father disowned me when I began transition. He was unable to understand it, but neither could I, so there wasn't much I could do about that. He was unable to accept it. He broke all communication with me, but I gathered from others that he cited biblical references.
I knew he respected his minister, so I travelled to see the minister, a day's journey. I hoped to discuss with him the issues of transsexuality, and to find out if he supported my father's non-acceptance. If so, I hoped to change his mind through enlightenment, if not, I would ask him to intervene on my behalf.
However, when I walked into te manse, the minister very quickly launched into telling me he had serious problems with his christianity. I couldn't believe it: he started unloading on me that he didn't believe in god. I spent an hour counselling him, then left, mission voided.
Years later, my mum enabled a link between us, and I was accepted back into the fold, warily, but later, my father was to celebrate my happiness, and my beauty, even. It came full circle when, preparing some freezer meals for him while visiting, the new minister came to see my father. Busy in the kitchen, I just said Hi, made some tea for them and left them to it. Later, back home, my father rang me to tell me, with obvious pride, that the minister had asked him who that beautiful young woman had been in his kitchen. Unthinkable years earlier, given time, things can change.
In answer to te specific question, i'm unbelievably happy in my new gender. It's been ten years, and still a day doesn't go but that I appreciate my womanhood, my gender, my taking of my femininity. I'm not even jealous of born-women, my journey has been interesting, fulfilling, rewarding. I wouldn't swap it for anything.
