Unfortunately this doesn't seem to be the case with churches I've come across. I've come across churches who have openly preached against homosexuals and transsexuals as being 'evil fornicators', freaks and even paedophiles.
As well they should if they sincerely believe doing so maintains integrity to the fundamentals of what they have covenanted with their God to uphold.
If you come among them seeking to subvert them from what they believe is their fundamental responsibility to their God, is all you can hope to gain there is turning them into infidels. So, if you had your way there, do you really want the company of infidels to the God they profess means everything to them?
That is why I say you would be fine among them if you are wishing to join in with them and seek to be in harmony with the terms and conditions of the covenants those organizations are bound by. They will receive all who are striving to overcome whatever weaknesses they suffer with if their hearts are pure and they are seeking the ideals of the religious organization.
But, if you come in there seeking to press your personal agenda and expect them to lay aside their whole premise for being of that faith just so you will feel good about yourself is a bit disingenuous.
I wouldn't personally mind giving up on gender reassignment and actively practicing a religious belief which does not recognize it IF someone would be willing to actually discuss with me why I should do so without simply chanting Bible/scripture verses at me.
Most religious organizations are built upon the authority of what is in their sacred texts. They are letting you know that to be in harmony with their organization that you need to have integrity to what they hold as authoritative.
Think of a church like the wife of God. She is under covenant to nurture and succor all those who wish to be spiritually born of her Husband. His spirit is manifested in the word (semen) she holds as authoritative. If you try and seduce her to receive the word (semen) of some other source of authority as what she should be nurturing then you will have caused her to commit adultery against her Husband and you will make your own spirit by way of that the soul of an adulterous union.
I am who I am. I can't change that with a sledgehammer.
That's another way of saying: "I have no choice".
And the fact is that I cannot really know whether I've made the right choice in this situation until I've done it and either chosen to practice a specific faith and abandon my LGBT life or undergone the surgery.
That's another way of saying: "I can't know if something is sinful or not until I actually do it."
And certainly in one case, it's an irreversible decision.
Thankfully you are not entirely overcome by the two spirits I identified above.
You do need very serious help and I am not so sure any religion is up to the task on what you will need to at least come back to a place where you are operating out of choice and out of belief that you can know what is best for you prior to "just doing it".
And, this really isn't so much as a religious matter as it is you having the faculties of mind and heart to take control of your life back from whatever it is that has you of a mindset to totally surrender your choice.
I was describing what I invariably observe when having conversations with people dealing with same sex attraction and other abnormalities in the sexual orientation area. It usually doesn't take long before they boil the discussion down to "I don't have a choice". Then, at that point, the sexual abnormality is the least of my concerns. If a person has given up that they have a say in what they can and cannot do in life, that is a far more grave and serious issue than sexual orientation.
