This is one of my favourite points to bring up. According to text I read once there was a pharoah that wanted to be referred to as a woman and was in search of a surgeon to alter their genitalia, but I can’t for the life of me find the source. (EDIT: The name is Akhenaten) Even without that there is another pharoah (masc) called Hatshepsut, and many other examples of cultures before and during ours that did/do not care so much about personal expression, much less police it.
