Why has legal sex always been restricted only to what was assigned at birth only based of gonadal sex? Never from other equally valid (polar/binary) sex definers, such as cerebral sex (BSTc), social sex, hormonal sex, modifiable phenotypical sex, biological sex, cerebral sex, chromosomal sex or/and somatic sex ?

All humans have -all- of these -sex identifiers- but not all individuals have -all- of these identifiers aligning on the same side of each sex definer's polarity.

People have allowed the state to assign a legal sex from gonads observed at birth since identity documents appeared; as if gonadal sex was the only reliable sex definer to mark a legal sex; though every individual carries all the other sex definers.

Let's not ignore phenotypic plasticity.
Humans are not passports.

Saw thread on FB, had to search, TLDR for now:

> Turns out there is only ONE GENE on the Y chromosome that really matters to sex. It’s called the SRY gene. During human embryonic development the SRY protein turns on male-associated genes. Having an SRY gene makes you “genetically male”. But is this “biological sex”?

Kurt Vonnegut might have mentioned a number for human sexes....
