I don't pretend to be an expert on transgender issues. I'll tell you right now that I'm not completely sure how transgender people function, I only know of their social stigmas and their battle for equality.
I do know enough, however, to spot a problem at school. There is a girl at my school who is genetically male, but identifies as a straight female. She is the subject of much ridicule, including from one of my very best friends.
She says that you can't argue with your chromosomes. God put you in your body to be that sex. I told her that isn't how it always works. She still didn't understand that transgender people can't help their genetic material being different from who they are inside. Kind of like how a can of soup with an incorrect label can't help that it's tomato when it's labeled cream of mushroom.
