You can’t be transgender any more than you can be a unicorn or a sorcerer. You are born male or female. Period.
What I really, really wish for is that Obola and Moochele would declare themselves eagles, climb to the top of the Washington Monument, flap their ‘wings”, screech like eagles, and jump off, taking their vile spawn with them for flying lessons. Then I’d wait for the giant SPLAT! and laugh my behind off.
You can be more feminine or masculine though, which doesn’t mean you are the opposite of the sex you were born, it means you are a feminine male or a masculine female.
God made them male and female.
Lately I have wondered if the reason why that is, is because our gender continues on into eternity. That though marriage as we know it is not there anymore, that some kind of intimacy with one another is not only possible there, it is to be celebrated as can not be in this present world. God did make sexual pleasure after all, and He called it good. No reason why it won't go on just like eating food will be there also.
Claiming to be another gender than what He has provided, or homosexuality or bisexuality, is a grave violation of that eternal identity. Maybe that's one of the reasons why God condemns it.
(Just thinking out loud. I'm not the greatest of theologians.)
