The problem is we can't really categorize people in the past. Was the Chevalier d'Eon[0] for instance a straight man who cross dressed, a homosexual man who dressed in feminine clothes as an expression of his homosexuality, or transgender? Karl Heinrich Ulrichs[1] is often thought of as one of the first homosexual activists but the word homosexual didn't exist at the time, he coined the phrase Uranian to describe himself and identifed as a female psyche in a male body, so should we say he is gay or transgender? Trying to retrospectively put people into categories that didn't exist when they were alive is impossible.
