If you think transgender is a social phenomenon, then your own sexual orientation should also be such a phenomenon, and that perhaps only society shaped you into a heterosexual.

i understand that you are heterosexual - I am too. But the above assumption (that society makes people hetero) probably seems totally absurd to both of us.

I bet you cannot remember any point in your life where you had to or could decide if you wanted to be homosexual or hetero. Something like that just never happened. Without ever thinking about it you simply fell in love with the opposite sex at some point, and then again and again for the rest of your life, and nothing could ever have changed that. The same with me. It´s purely biological.

Homosexuality has been found in 400 animal species, where you can rule out any "social phenomena", and its percentage in the human population is consistent in all nations, cultures, and societies. That figure alone proves a lot.

It´s the same with transgender/the problem of gender identity. Small, but consistent, stable percentage across all nations, cultures, and societies.

We all have the genetic material of both our parents. My mother loved men, my father loved women. Both these tendencies were in me as a potential right from the start, but the sexual appetite for men had to be deleted in me early on, the same way that my mother´s feeling of gender identity (she clearly identified as a woman without any doubt) had to be turned off since I was to become a man.

Now every single procedure of the millions in the development of a child can go wrong. What if my mother´s sexual appetite (for men) had not been turned off as I grew into a man, and instead my father´s appetite for women had been? Then I would be gay.

Most things sexual are a matter of biology. Mother nature simply couldn´t afford leaving the crucial process of reproduction up to the unreliable decisions and tendencies of human societies.

When I was young, I had to study developmental psychology for the exam that let me do what was later my job. The textbook back then firmly stated that puberty is just a social phenomenon of industrial societies, and has nothing to do with biology. Today we know, that puberty is all about biology, that that textbook was all wrong, and that in puberty the brain is rewired completely to perform adult mental functions; the errors, confusion, and chaos typical of that period in life cannot be helped - they arise because the brain is a construction site.

Think of the example next time when you believe something that has to do with instincts is heavily shaped by society. It usually isn´t at all. In such respects, we are animals.
