It's amazing to me that you can understand exactly the situation historically, and yet stubbornly insist on warping your perspective based solely on who you want your words to support.
All perspectives on history are warped. It's kind of a built-in feature of history itself. We don't study history for the benefit of dead people in the past, we study it for people in the present, because we
are people in the present and no exercise in imagination can make us anything else.
There aren't trans people through history, because the concept of gender that does not allow for ambiguity, against which people can be classified as trans, did not exist.
Depending on how far you go back, basically no concept which matches our modern understanding exists. It all becomes resemblances. History necessarily involves a process of translation, and that's true of everything, not just gender.
And by saying there are no trans people in history, while technically correct, what you're implicitly doing is letting cis people off the hook. Cis people, like trans people, necessarily live in the present, and in the present cis people have learned to view their own sexual identities as natural and uncontested, as something that just exists and has always existed and always will. But that is not the case. Sure, men and women existed and they had penises and vaginas, but again, even saying that is a
resemblance. People in history did not have the same understanding of what a penis was as a modern person.
But it also allows for another sneaky little myth, that historical accounts of sex/gender are somehow more ambiguous and hazy than our modern ones, that everyone just kind of existed in this genderless liminal space waiting for real big boy science to come along and show them the truth. That is very sadly untrue. The concept of sex in many historical societies may be incomprehensible to us, but it was absolutely real to the people who lived in those societies. Huge numbers of books were written on how to classify men and women for the purposes of applying religious law, and those laws could be and were violated very easily. The punishment for violating those laws was, for many people, literally being burned alive, or if you were lucky, being mutilated and exiled. It was a very real, very arbitrary and absolutely inflexible system of belief.
Also, as alien as the pre-scientific understanding of sex might have been, some of its implicit features have not changed.
Everyone at this point accepts the concept of sex as an empirical observation to explain the biological mechanism of reproduction. That is, however, not what sex means in this society we live in. It is never what sex has meant. Before anyone knew what an ovum or spermatozoon or a sertoli cell was, sex still existed, and it described (much as it does today) a strange and completely unscientific point at which the features of human bodies, the interior nature of human beings, and the purpose for which human beings were put on this earth magically and conveniently intersected.
If you're going to continue to believe that history was populated by "men" and "women", and that this system of classification, and the imagined difference between these two types of person both then and now, were anything more than a laughable consequence of a defective understanding of biology, then you have no right to talk about people warping their perspectives.
