Constance, we are slowly discovering the biology that underlays gender orientation. This is a process inevitable, and limited only by the edge of technological advancement.
Most importantly, it is the same curve of advancement that has existed for other things that were once considered evil, the results of demons, etc. and are now seen as the reality they have always been.
In a generation or two, we will look back on those who thing that gender variance is a moral evil, failure or choice as the beknighted ignoramuses that they in fact truly are. They will be in the same drawer of history that contains those who opposed the civil rights movement, those who owned slaves and used the Bible to justify it, those who thought that epileptics were possessed by demons rather than simply the denizens inside a chemically unbalanced brain.
I have tried and tried and tried, over and over, to show you in everyway possible and all the ways you judge yourself and your own righteousness that my gender orientation does not impute to me any greater or lesser moral evil! Because it is not a matter of inherent morality! Anymore than your own gender adds any sort of moral texture to your own spirituality!
Isaiah 58 comes to mind as a pretty good list of things that would actually be far more pleasing to God than writing letters to people that boast about rivers that you will not cross or that conflate your own sexual proclivities and addictions with my gender orientation!
Directly speaking, I strongly exhort you to have the faith of your convictions and humble yourself and simply love. Cross rivers. Swim oceans.
But have a care not to make your converts twice as fit for hell as you are yourself.
