When I was a kid there was only one openly trans person I would ever see. A man at the library who wore women's clothes (to put it in the terms we would have used then). They didn't try to be feminine beyond the clothing. Very occasionally some makeup. Legs were not shaved etc.

I was at the library on a weekly basis and saw this person all the time but it was just this one person. My mother told me not to stare or make fun of them and that they weren't hurting anyone and could dress how the pleased.

Now, some forty or more years later I frequently encounter non-binary people, trans people, etc. I follow the same method my mother taught me. They are just people living how they want.

It is interesting to be that William Gibson had trans characters in Johnny Mnemonic, for example, written in 1981. That's around when I would see that person at the library.
