@cmclymer The only upside I see to that manifesto of ignorance is that her transphobia is aaaaalllllll out in the open now

I mean it should have already been obvious, but now it's undeniable
@cmclymer If you'd like to learn some history and science of gender identity from a nonbinary genomics PhD, here you go fam:
@cmclymer You know, not everyone is going to read a pdf & I need to process my JKR-induced rage productively, so here's the Twitter version!

tl;dr Biological sex, sexual orientation, gender identity, and gender expression are distinct concepts and more complicated than you think (1/x)
@cmclymer Biological sex is not binary as most people assume

Intersex people exist - ~1 in 1500 births, which is an underestimate since many do not find out until later in life, some never do (but autopsy reveals it)

The boundaries of biological "maleness" & "femaleness" are fuzzy (2/x)
@cmclymer Fuzzy how? Sex isn't just determined by external genitalia, but by chromosomes, hormones, internal reproductive organs, and secondary sex characteristics.

How small does a penis have to be to be considered intersex? How big a clitoris? Those are culturally defined (3/x)
Even chromosomal sex is not binary. X0, XXY, and more combinations of sex chromosomes exist

There are women with XY chromosomes because their SRY gene, which starts development toward being a male, is either broken or deleted (4/x)
Biological sex is not the same as gender identity. Gender identity is an internal, deeply held sense of gender

Gender identity may or may not match biological sex

Gender identity may or may not fit into a binary (5/x)
And not that science has to legitimize a group of people's existence, but for those who make the "it's a choice / a cultural virus" argument:

It's not.

Neuroanatomical studies support the existence of trans gender identities (yes I'm dropping citations) tandfonline.com/doi/full/10.31…
Additionally, a study from earlier this year found 21 genetic variants associated with being trans

Some are involved in estrogen receptor pathways and are possibly involved in brain development (6/x) sciencedaily.com/releases/2020/…
And historical records of trans and nonbinary people exist throughout history!

Sumerian and Mediterranean (4000 years old)

Ancient Egypt, Greece, Rome, India, and Thailand

Judaism always has had distinct language for nonbinary and intersex people! (7/x)
Why don't we hear about any of this? Why do people like JK Rowling think transness is some mind virus?

Because NAZIS BURNT DOWN the leading research center on trans issues!

Scientific research was estimated to be put back by decades (8/x) teenvogue.com/story/lgbtq-in…
Thousands of scientists who are experts in genomics, health, and other relevant fields stand by the explanations I've made above. They are not controversial among the scientific community

Do not let TERFs weaponize science to support their bigotry not-binary.org/statement/
One final note: The pdf of my original Pride presentation includes tons of references and educational materials compiled by me and my LGBTQ science/engineer coworkers!
