There are no men who want to become women.
And there are no women who want to become men.
If a child is born with an intersex condition resulting in ambiguous genitalia, the best practice is to allow that child to grow up without surgically altering their genitals until they are old enough to say If they are a girl or a boy, or even neither. I hope you’d agree this is right and humane.
Some babies are born with a different sexual ambiguity that can’t be seen at birth. Their brains may be one sex and their genitals are the opposite. They too can tell you which sex they are, but their bodies contradict them. Can you imagine how distressing it is for a girl to grow a beard and have her voice break, or a boy to start having periods and breast development. This is the reality for thousands of people, many are too ashamed and depressed to even ask for help. They spend years living in misery and many attempt suicide.
A man would never want to be a woman, but a trans-woman isn’t a man. She just has the misfortune to be born with a male body. She will tell you that if only you’ll listen. Similarly, no woman would choose to be a man, but a trans-man isn’t a woman. He just has the misfortune to have been born with a female body. He will tell you that if only you’d listen.
Please start to see that trans is not a choice. Hiding it or coming out is, and the recent increase in numbers is because more people are feeling confident to come out of hiding and ask for help. This is because society is generally wiser now about human diversity, and realises the misery that intolerance can cause.
