To be fair with the commenter you are replying to and as someone who absolutely don’t care about your silly American cultural issues, this use the word gender by sociology is a modern one which redefines its meaning. Historically the word is indeed strictly synonymous with sex.

I still believe that the insistence on erasing previous meanings rather than just using new words is 90% of why the USA is such a cultural cesspit and any kind of discussion turns into a battle but that’s only me.

In many languages, like German (which may be GPs native language), those two things share the same exact word, requiring modifier words like "biological" to differentiate between the two, making everything a bit confusing when crossing the language barrier.

You're right, apologies for the mistake.

Even that's not really cut-and-dry. I don't normally like linking to twitter, but this thread is amazing (scientific) content: https://twitter.com/rebeccarhelm/status/1207834357639139328?...

It appears that way, but skirts around the gametic model of discerning biological sex that is the golden standard for other species, while elevating the status of chromosomal defects.

It’s a good example how selective presentation of scientific realities can be abused to mislead.

Chromosomal defects in a binary system don’t constitute a new or between-state, and it also isn’t commonly described that way: XXY (Kleinfeltner) affecting males is the mainstream position.

Totally agree, I was responding to the twin assertions that gender is based in genetics and that there only being two is widely accepted.
