It is not so much that trans advocates, or persons who take the identification of trans-man, or trans-woman, are picking a fight with the biological designations of genetic inheritance, reproductive capacities, or gamete functioning. They are claiming rather, by the use of the word “trans,” that these chemical or biological realities have no social importance and no desirable bearing or impact on their life. We may try to describe the claims as a-biological, verses anti-biological or anti-science.  They are moral claims, and not ontological claims.
