You seem to be saying that people can, if they desire, change their sex. That is unequivocally false.

To use your analogy: if I have a McDonalds, all I can every produce is hamburgers. I can change the sign, and the paint. I can change the front door and the decoration; i can change lots of visual things about my store, but it will only ever have a grill, and buns, and I’ll only ever make hamburgers. I can even fill the place with chemicals so hamburgers stop being made, but that doesn’t mean I’ll ever make tacos.

So your analogy doesn’t work. A male can get a sex change and make all kinds of visual changes, but it doesn’t matter: his body is organized around producing sperm. He will never have ovaries, nor will his body every have the required equipment to make anything other than sperm.

What you are talking about is just changing the decorations. That doesn’t change the fundamental thing, it’s just a pretense, an act, a facade. It can be a convincing one. It can fool people into thinking they are eating at a Taco Bell, for sure. But if the fundamental differentiator of the McDonalds is the hamburgers… well, the it’s still a McDonalds.

Experience, desire, and all the surgery in the world can’t change that.
