Literally every sentence you typed is entirely inaccurate. It's bad science promoted by bigots to create a convinient lie that permits them to discriminate and oppress people.

Edit to add: It's even a bad interpretation of the metaphor. It's like saying "akshually, there's only two atomic particles, the proton and the electron, and these are the only two particles that determine charge, so there's really only two types of atoms, positive and negative charged atoms, and that's why black people don't deserve civil rights."

That's you. That's what you sound like.

• Human genders are not defined by gamete types.
• Human sex is not defined by gamete types. There are women born with testes, and men born with ovaries. Secondary sexual characteristics are influenced by hormones as much as genetics, and the presence of a gamete does not determine the hormones in a person's body.
• Sexual development charts are generalizations across average humans, and do not necessarily represent any one individual's sexual development. Everyone does not fit into a box.
• You can't hide your bigotry behind peer-reviewed biology papers and textbooks. The actual science doesn't support it.
• Gonochorism is not relevant to the psychosexual development of humans. It's a term used to differentiate animals that change sexes due to environmental factors, like alligators and snails. Nobody is claiming that transgender individuals are simultaneously hermaphroditic. It's a biological strawman argument that belies the insincerity of your argument.

In short, fuck off with your nazi bullshit.
