Hi Ravensgirl.
First, Transgender is not a choice or a lifestyle. It is not something that a child picks up from watching television and sees some advantage to it and says, "You know what, I'd like to try that because it looks better than the life I am living now." That just does not happen. If Caitlyn Jenner did anything, she made it possible for some of us to stop slowly killing ourselves by hiding who we are from the rest of society.
I know this only too well. I am male to female transgender. I spent 47 years (since I was 5) trying to be the man my father wanted me to be, and it darn near killed me. For the past ten years I suffered panic attacks, anxiety attacks, TMJ, GERD, early onset arthritis, and high blood pressure, and was physically dependent on beta blockers, and taking tranquilizers. I tried everything I could think of to deal with it, including sports, hobbies, marriage, children, family, yoga, meditation, tai chi, religion, denial, and alcohol.
I remember asking myself an existential question at one point: "Transition is probably going to cost about $100,000 at your age. Why not just buy a nice used Aston Martin or Ferrari? Which one would you like to use the money for?" I ended up going shopping for skinny jeans and makeup.
When I finally put aside the shame and guilt and started expressing my femininity, my blood pressure went back down to normal and I stopped needing the meds.
At the same time, I love my wife. So I guess that makes me a lesbian. When I was younger, the confusion of gender with sexuality was part of the denial. "I'm not attracted to men. I'm not a gay man. How could I want to be a woman? How could I be transgender?" Then at some point I learned that being lesbian and transgender was a "thing."
If you want to bring God into the mix, then consider this: Jesus Christ Himself never condemned homosexuality, even when asked what the sins were. He also said the rules of the Old Testament (specifically Leviticus) were the rules of men, and that they no longer applied, and it is what is in a person's heart that mattered. And as far as the later writings of the Apostle Paul, we have a lot of reasons to believe that the condemnations against homosexuality were added by others after his death, and/or deliberately mistranslated from the original Ancient Greek.
I don't think this is God having a sense of humor. I think this is God saying "When I said 'Be fruitful and multiply' I didn't mean keep doing it until you overrun and destroy the rest of Creation." A lot of animals tend to have homosexual pairings when populations get too dense. It is a natural form of population control, and a far better one than disease, starvation or cannibalism. God created those animals, and they are not sinners. They are just animals doing what they were designed to do. Do not listen to manipulative "Christians." If you believe in intelligent design of animals, then you have to look at animal research and believe that homosexuality is part of the design as well.
God created you, and your children. And he loves you and them.
Peace, Carly
