Really informative post. I have a degree in BioSci so this perspective wasn’t new to me. But I appreciated how you layered the science with our cultural conversations about gender and how we can love people best. Thanks.

Your piece would be a lot more useful if it included any numbers. No biological (and more broadly, no physical) system is ever literally binary. Even the "binary" bits that are operating the screen you are reading are not literally binary, just a very, very close approximation to it.

Approximately 99.85% of humans are born with XX or XY chromosomes. (The other observed combinations, predominantly X, XXY, XYY, and XXXY) are abnormalities that collectively comprises something like one-tenth of one percent of all humans.

Your point is pedantic.
