I’m not sure I understand. Where did I say historically intersex bodies mean they’re trans? …are you talking about the grave found in Suontaka, Hattula in Finland? Because they did DNA testing and discovered the deceased had Klinefelter syndrome, which to very crudely summarize (and I apologize if I say this incorrectly) is someone mostly male-presenting with an additional copy of the X chromosome; so XXY instead of XY chromosomes. The deceased was dressed in female clothing of the time, and in the grave they found jewelry attributed to women in that time as well. That’s why they theorize the individual might have been trans as well.
