To be clear though, hormones don’t define how your body functions, that’d be DNA. You wouldn’t have hormones or the ability to process them into meaningful signals without DNA. Ultimately, “biological sex” is determined by the sex chromosomes, which never change. I’m not arguing whether or not right-wing chuds co-opted the term (I’ve no clue, I don’t listen to right wing chuds), but it does have an objective, scientific, apolitical, societally functional meaning.
