@Torsten says Or a hermaphrodite.
Or a person with Klinefelter syndrome (XXY).
Or a person with Turner's syndrome (X0).
Or a person with genetic mosaicism.
Or a person with androgen insensitivity syndrome.

According to Dr. Anne Fausto-Sterling, a recognized expert in this field of study, 1-1/2 to 2% of all births do not fall strictly within the tight definition of all-male or all-female, even if the child looks "normal." In reaching her numbers, Dr. Fausto-Sterling counted all incidents of intersexuality, from mild to extreme. The incidence of children with mixed genitalia is pegged at 1 in 2,000 to 1 in 3,000, or 0.033 to 0.05 percent of all births.

I would point out that knowledge is situational and cultural, not necessarily "truth."

For example, it was once feared that sailing a ship too far might result in falling off the flat earth.

What we know would be better described as "what we think we know."

Anyone interested, part of the Introduction to "A Zen Reader" (Thomas Cleary):-

Zen is traditionally called the School of the Awakened Mind, or the Gate to the Source. The premise of Zen is that our personality, culture, and beliefs are not inherent parts of our souls, but “guests” of a recondite “host,” the Buddha-nature or real self hidden within us. We are not limited, in our essence or mode of being, to what we happen to believe we are, or what we happen to believe the world is, based on the accidental conditions of our birth and up-bringing.
This realization may not seem to have positive significance at first, until it is remembered how much anger, antagonism, and grief arises from the ideas of “them” and “us” based on historically conditioned factors like culture, customs, and habits of thought. Any reasonable person knows these things are not absolute, and yet the force of conditioning creates seemingly insurmountable barriers of communication.
By actively awakening a level of consciousness deeper than those occupied by conditioned habits of perception, the realization of Zen removes the strictures of absolutism and intolerance from the thinking and feeling of the individual. In doing so, Zen realization also opens the door to impartial compassion and social conscience, not in response to political opportunity, but as a spontaneous expression of intuitive and empathic capacities.

Yeah you get observed at birth, it's basic biology. But you know how people who deny science are. They only agree with science that agrees with them.

at birth, physical bodies are brought into the world

physical bodies have properties

the properties of bodies differ

and you're not born "you"
self-identity as a feeling comes much later

in modern society, social identification is primary at birth

e.g., a name has gender
etc.

Truth bomb. Painful for many to read though no doubt 🤷

@Annie13 Where did I say it didn't? You cannot change your biological make up though!

I was a female foetus long before I got the gender " female" when born...

Not always the case. If you know anything about genetics and chromosomes you’ll understand there are anomalies. Yes there is a social learning element that is inflating prevalence rates of gender diversity but that will settle.

Assigned anything at birth? Means?

Are u addressing someone in particular?

Keep up the good work, you are hitting the nail on the head quite consistently
