No one told me I was trans. I wish someone had told me when I was young enough for it to have mattered. And the message I got from society certainly wasn't, "You might possibly be trans." It was, "Yes, there are a few trans people and they are freaks and jokes and you can't possibly be trans."
I hope that might have improved a little. I think some kids get a more balanced message, like, "There are trans people and that's okay." (That's slightly sarcastic.) Hell, "Trans people are freaks and jokes," is still an improvement over, "There are no trans people."
But sweet fuck, statistically speaking, no one is telling kids, "You are trans." No one is even telling them, "You might be trans." That's a made-up fear. But again, the people who made it up know that.
