Please can we have a link to a science based article that states a case of someone spontaneously changing genitalia that didn't involve late forming genitalia or medical intervention to correct genitalia malformed by a genetic disorder.
I think you are talking about intersex or DSD here? In which case scientifically speaking they are still one or the other sex category, male or female.
Sex is very clearly defined, you can google the scientific definition or look in any basic biology book all the way up to the most in depth scientific journals and you will find zero evidence that anyone can change sex, but you'll find loads that state definitively what sex is.
I also would like to extend a challenge to you, who think I am bigoted for stating a scientific fact, to find one single post where I have actually been transphobic or bigoted in any way.
I fully believe in Trans peoples existence and right to an existence. I believe they deserve their rights and to live their lives free from prejudice, discrimination or violence.
I also believe in science. I believe that sex is definable by science and is immutable.
Nothing in the last sentence makes me a bigot.
What you have been saying is provably wrong.
