🧬 Biomed experts mobilizing scientists to fight transphobia through education 🏳️‍⚧️ 🌐 beyondxandy.org ✉️ info@beyondxandy.org

We're brainstorming ways to support trans folk in biomed by forming more community and networking/mentoring opportunities Would folks be interested in a Discord channel to bring folks together? Or are there other platforms people would suggest?

My husband has taught human reproduction and development to the Cambridge medics for over three decades. When people start banging on about "only two biological sexes" he starts with "which sex: genetic, hormonal, or gonadal"? Biological sex is not binary. www.scientificamerican.com/article/sex-...

Sex Redefined: The Idea of 2 Sexes Is Overly Simplistic

Biologists now think there is a larger spectrum than just binary female and male

scientificamerican.com

we made a critical error allowing reactionaries to make-up concepts like “biological sex” and frame them as non-ideological when it’s the exact opposite: people who undergo HRT *are literally changing their biological sex.* this is not some philosophical distinction, it is actual biological reality.

This will simultaneously cause a massive testosterone shortage for transmasc people And leave thousands of military personnel with fertility issues for being unnecessarily put on T Which is the goal. Those in charge see military members as lesser and expendable. Part of their larger eugenic plans

Hegseth announced they're gonna start screening for T and administering testosterone treatment for warriors found wanting

Chromosomes are biological. Hormones are biological. Anatomy is biological. Behaviour is biological. Reifying one of the many aspects of sex as the only true definition of ‘biological sex’ is a political statement that I refuse to endorse.

Clarence Thomas is not a biology expert Sex is bimodal - it's why intersex people exist Sex is mutable - it's why HRT works Transness is innate - it's why we have existed throughout human history and across cultures He and the court are the ones who lie

Clarence Thomas's concurring opinion in the trans sports ban case in West Virginia contains some of the ugliest transphobic stuff I have ever seen in a legal opinion. Straight-up gleeful. Vile man. www.supremecourt.gov/opinions/25p...

2 WEST VIRGINIA v. B. P. J.
THOMAS, J., concurring
judgment). Because “gender dysphoria” is a mutable men-
tal state that is the object of psychiatric treatment, it does
not resemble the immutable characteristics on the basis of
which our precedents have applied heightened scrutiny—
race, sex, or national origin. Instead, gender dysphoria re-
sembles other characteristics on the basis of which legisla-
tures may classify with a merely rational basis. See, e.g.,
Heller v. Doe, 509 U. S. 312, 321 (1993) (mental illness);
Plyler v. Doe, 457 U. S. 202, 220 (1982) (immigration sta-
tus). Legislatures have many obvious rational bases to
keep men who believe that they are women out of teams
and private spaces reserved for women.
Second, as the Court recognizes, this case concerns “bio-
logical men” and “boys who identify as girls.” Ante, at 10,
27. Men and boys with gender dysphoria are not women or
girls, even if they believe that they are. Sex is an immuta-
ble “biological” characteristic, see ante, at 10; it is binary;
and “man” and “woman,” “boy” and “girl,” are the terms that
correspond to adults and children of each sex. See A. Byrne,
Are Women Adult Human Females? 177 Philosophical
Studies 3783, 3786–3787 (2020). To use language to ob-
scure reality—to show “indifference regarding the truth”—
is to lie to the public and cease to treat our fellow citizens
“as equal[s].” J. Pieper, Abuse of Language—Abuse of
Power 17, 21 (1992).

Before I transitioned, I ironically was accused of being a secret trans woman all the time simply because I was 5'11" Are all tall girls going to have invasive genital inspections or unnecessary genetic testing now? What a sham of a ruling devoid of both logic and empathy

The ban is heinous for what it does to transgender athletes. But if you think cisgender girls and young women won’t be caught up in the fallout, too, you are woefully ignorant

“I founded @beyondxandy.bsky.social not because I think scientific arguments will convince the far right. But some people do still trust science, and need real information out there to combat propaganda. I've had hundreds of people tell me I've changed their mind just from explaining the facts.” 🧵:

Yesterday I had the honor to speak at Chicago's Trans Liberation March about @beyondxandy.bsky.social I thought I'd share my speech here: Us trans folk often joke that we need to learn the equivalent of a PhD in biology just to defend our existence. Well, I actually went and did it. 🧵 1/X

Hello! I AM a biology (genetics) expert and can confirm 100% of this is true. I've seen firsthand hundreds of differences in sexual development (dsd's) in dogs. It's leaning into grade-3-level misconceptions of biology that drive these politically motivated decisions.

Are you an actual biology expert that understands why sex is not a simple, immutable binary? Quote our post below with examples from your area of expertise We need more scientists speaking up against this nonsense. Propaganda must be countered with actual biology! 🧬

Without even taking into account the fact that sex and gender are not the same thing, there are so many more sexes than male and female. Someone could, for instance, have an XX karyotype but one of their X chromosomes has a fused SR-Y gene resulting in them looking like a man, despite being XX.
