>Muh science. Need proof to believe things. But genitalia doesn’t define gender and “I can be a girl today if I feel like it”
Gender taxonomy is what you define as genitalia, but the liberals look at the medical literature for.
The following systematic list gender taxonomy illustrates the kinds of diversity that have been studied and reported in medical literature. It is placed in roughly chronological order of biological and social development in the human life cycle. The earlier stages are more purely biological and the latter are more dominantly social. Causation is known to operate from chromosome to gonads, and from gonads to hormones. It is also significant from brain structure to gender identity (see Money quote above). Brain structure and processing (biological) that may explain erotic preference (social), however, is an area of ongoing research. Terminology in some areas changes quite rapidly as knowledge grows.
-chromosomes:
46,XX (genetic female); 46,XY (genetic male) ;45,X (Turner's syndrome); 47,XXY (Klinefelter syndrome); 47,XYY (XYY syndrome); 47,XXX (XXX syndrome); 48,XXYY (XXYY syndrome); 46,XX/XY mosaic; other mosaic;
-gonads:
testicles; ovaries; ovarian and testicular tissues, not in same gonad (true hermaphroditism), ovotestes, or other gonadal dysgenesis;
-hormones:
androgens (including testosterone, dihydrotestosterone, etc.), estrogens (including estradiol, estriol, etc.), antiandrogens, progestogens, and others;
-primary sexual characteristics:
genitals (genital development);
-secondary sexual characteristics
dimorphic physical characteristics, other than primary characteristics (such as body hair, development of breasts); certain changes in brain structure due to organizing effects of sex hormones (Is it useful to view the brain as a secondary sexual characteristic?);
-gender identity:
one’s sense of oneself as a man, woman, or gender non-conforming;
-gender role:
social conformity with expectations for males or females;
