And you -- and Emma Hilton & Colin Wright -- saying "eventually produces" or "previously produced" as criteria for sex category membership doesn't make it true either. Only your "misinterpretation". As saying that 2+2=5 doesn't make that true. As saying that freemartins are female doesn't make that true either:You saying it multiple times doesn't make it true. Your "standard" definition is NOT the standard definition. It's your personal interpretation, based on what you are assuming beforehand then wedging the definition into.
A freemartin or free-martin (sometimes martin heifer) is an infertile cow with masculinized behavior and non-functioning ovaries. Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-Müllerian hormone from the male twin.
Freemartin - Wikipedia
"phenotypically female" is not the same thing as "reproductively competent", the sine qua non for sex category membership. At least by the standard biologically definitions which are published, and utilized, in reputable journals, encyclopedias, and dictionaries:
For instance, a mammalian embryo with heterozygous sex chromosomes (XY-setup) is not reproductively competent, as it does not produce gametes of any size. Thus, strictly speaking it does not have any biological sex, yet.
