Hanno I had the same ignorance that you have understanding the difference between sex and gender. They are not the same thing. Exhaustive medical research has defined the differences. I will rely on them.
I did not just wake up and decide that I am a woman so your statement of a middle age crisis is absolutely invalid. It been a lifelong , painful experience from my birth. I would rather be cisgender, believe me that is a much easier path.
Transgender suicides and death define a life path of broken emotional glass. You would not elect to walk it.
I accept that I am not you and you are not me. I will assume that we will not come to an agreement.
Maybe I am overly sensitive to hate.
I wish you peace and happiness.
