Then you and your census-taker are using non-standard and non-scientific definitions.
Non-standard? The U.S. Census is mandated by the Constitution and has occurred every 10 years since 1790. Separate counts of males and females has been part of that census since the very first one. Show me where the U.S. Census Bureau has ever excluded pre-pubescent girls and post-menopausal women from the count of females due to their lack of gamete production. One hundred seventy-four years of consistent usage by a constitutionally established government bureau sounds pretty "standard" to me. About as standard as it's possible to get, in fact.
The issue is how we are to DEFINE "male" and "female". And the ONLY definitions that hold any water at all are the biological ones, the ones that say that to have a sex is to have functional gonads of either of two types, those with neither being sexless.
Show me your track record of successfully applying your preferred "biological" definition to real-life situations.
Show me where you or defense lawyers acting on your behalf have gotten women acquitted of crimes because the police reports or indictments described a suspect as "female" when the suspect was actually post-menopausal, sterile, or otherwise "sexless" and therefore didn't match the description or represented a mistaken identity.
Show me where you've convinced business owners or public agencies to provide separate facilities labeled "sexless" for employees and customers who lack functioning gonads or ovaries.
Show me the medical record keeping software systems or installations you've arranged to be configured to omit "male" and "female" from the data records of prepubescent children, post-menopausal women, castrated males, and others with injuries or disorders that preclude gamete production, designating all of them as "sexless" instead.
Show me where you've successfully petitioned the International Olympic Committee or any nation's Olympic Committee to exclude prepubescent athletes from any men's or women's event on the basis of their being sexless instead of male or female.
Show me the actuarial tables that you've successfully had altered to include the necessary "sexless" category, and which insurance underwriters are using them.
And then show me how your successfully implemented male-female-sexless designation system has persuaded individuals who
do produce gametes but claim to identify as sexless (e.g. "non-binary"), that they are actually male or female in accordance with a biological definition. How many such individuals have you persuaded?
