What is "gender ideology"? Also, biological sex in humans is actually kinda complicated and doesn't really follow your definition. See below:

* If males produce sperm and females produce ova, does this mean infertile people are neither sex?

* What are intersex people?

* Since females only produce ova before they are born, do only female fetuses exist, and birthed people with ova are not female anymore?

* What are people who are androgen insensitive?

* If biological sex is defined this way, why do medical practitioners not test for the presence of sperm or ova at birth?
