It’s not unusual to say something less controversial than what you wish you could say, so it tracks that someone who wants to say “I’m a boy” would say “I’m a girl who isn’t girly” in a time where the truth is presented as less of an option than it is today. It’s not that trans guys and tomboys are the same thing, it’s that the same label can be either true or a euphemism when applied to different people.
What gets me about the original post is it looks like it’s saying I as an unambiguously masculine man could wear a dress and be called ma’am by a stranger and when I respond “I get why you’d say that but I’m actually a man wearing a dress” then there’s an expectation the stranger might respond “don’t be ridiculous, that’s not a real thing. You’re obviously a trans woman.” I just don’t see this kind of scenario playing out.
The Terminator TV show feels the most prescient. They took a chess playing computer and said “This seems to play chess like a human would and that means it’s basically the same as human consciousness. Let’s try to teach it morality by talking to it and then have it run the military.”
Then it spent the rest of the series more interested in Lego Bionicles than Jesus and nobody on the project ever said “You know, maybe this thing that wasn’t at all designed to run the military is a bad fit for running the military.” They were just chilled by its indifference to their values and really hoped they could reason it into being something it’s not by the time they give it the power to kill everyone.
