While I have no issue whatsoever with Walt's decision, I question whether the spiritual connection can be credited with curing his disphoria. As a lifelong spiritual person, I have always believed there is a God and practiced my faith. I also have instilled the same values in my children. However nowhere during that process has my disphoria disappeared. So while I don't feel I am transexual, there is somewhere within me a strong connection to the female. That connection has been there from my earliest memory and all attempts at eradication have proven to be futile. This includes many hours of prayer hoping that it just goes away.
What I have instead found is that a healthy embracing of your transgender nature has been far more therapeutic for me than a "hold your breath until you explode approach. While I do not know the exact nature of the treatment Walt received, turning to Jesus Christ is something I have already done in my life. In addition I don't feel that there is anything particularly wrong with being transgender, most especially if you did not choose to be so in the first place.
Yes there are regrets for all of us but for some SRS has been a solution for their situation. I will not presume to speak for them. For people like myself there will be another path.
