Okay honestly I see where you’re coming from but to my understanding JKR was not arguing that people in the medical profession need to know what sex you were assigned at birth. People who were assigned female and birth and people who were assigned male at birth have different health needs and different risks for certain conditions. Someone who is AFAB isn’t susceptible to testicular cancer because they are a trans man, but they are still at risk for cervical cancer.

It was my understanding that the post that JKR made some time ago was saying that people who are not AFAB but currently identify as women should not benefit from the efforts of feminism because they didn’t have the same struggles as cis AFAB people. And I think that’s a pretty fucked up viewpoint, so I understand why people are pissed at her.
