JK Rowling is not an expert in genetics. But I am!
Chromosomal "sex" is more complicated than a simple binary. XXY women exist. Hell, XY women and XX men exist because of translocations of the SRY gene.

No, the point is that sex is bimodal, not binary. It is a cluster of multiple traits that tend to fall into two buckets, but not always.
The medicalization of intersex people has led to forced, nonconsensual surgeries and erasure of identities. Listen to actual intersex people

When you're writing for an app with limited characters, it's a conscious choice to phrase it this way instead of just saying "A student who is a trans man"
A conscious, transphobic choice
A student who said they identify as a transgender man asked Virginia Gov. Glenn Youngkin during a CNN town hall if he believes high school girls would “feel comfortable sharing a restroom with me.”
Here’s what the governor said.

Texas is already starting to investigate trans kids and their parents
This is not a hypothetical
This is real abuse by the state. This is a eugenics program intent on stopping people from growing up into trans adults
Traumatizing to watch this unfold
BREAKING: Texas has begun investigating parents of transgender children for possible child abuse for providing them with gender-affirming care.
Among the first is the family of 16-year-old whose mother works for the state agency responsible for such investigations

"Womxn" isn't inclusive
It invalidates:
-trans women by treating them as not-quite-real women
-AFAB nonbinary ppl as "women-lite"
-AMAB nonbinary ppl who aren't transfemme
-Trans men who are men
Just say "women and gender minorities" if that's what you actually mean

And last but not least, "mental sex" - what people generally call "gender identity"

"Chromosomal sex" refers to how many copies of X and/or Y chromosomes you have
XX and XY are not the only combo - there's X0, XXX, XXY, XYY, chimeras, and more
Sometimes people with XX chromosomes are AMAB, and sometimes people with XY chromosomes are AFAB (4/x)

"Sex" attempts to summarize many variables into a binary that works for most, but not all, cases

But sometimes Y chromosomes lack the SRY gene, and other times X chromosomes have a translocated copy (5/x)

Richard Dawkins both has the resources to educate himself and to provide a platform for trans authors to educate others
But instead he actively chooses to be willfully ignorant
