As I said, the world doesn't always resolve into simple binaries. It would be easier if it did, but it doesn't.
Actually, around sex classification it does. And for many reasons it is really important that people do not spread misinformation. I am sure that you have heard of some rather serious life threatening medical situations caused by people not acknowledging their sex which has led to at least one death, and several publicised other near death misses.
I am sure you are aware that even though the majority of the cells in your body are red blood cells, the other cells that control other functions of your body will still have the original codes for your body to function as the sex it was from a foetus. It is rather disingenuous to suggest otherwise really.
It is therefore vital for a person to be honest about their sex and the changes they have done so they get the best care. So, again. Stately that transwomen are female is misinformation and it is factually false.
And people with differences in sex development, those you point out that might have differences in their reproductive systems, are still male or female. That group have asked continually to not have their medical conditions politicised as explanatory conditions for trans people. With modern medical technologies and looking at a range of different organs, and body processes etc, they are categorised as either having bodies that are male and female.
