We need 2 questions answered:
What is the definition of "man" and "woman?"
What is the difference between "men" and "women?"
My position is that it is impossible to define these terms which include both trans men and trans women. I wish it wasn't this way, but I must yield to logic here along with the law of non-contradiction: something can not be both X and not X at the same time.
I really wish someone here would do it.
These terms can't be defined perfectly. Many terms can't be.
