The culture shift is stark sometimes when you watch old stuff.
On the other hand, don't let them turn that into an excuse. You know what dealt with trans rights in a pretty honest, raw, and understanding way, in the mid 1980s? Fucking Hill Street Blues. One of the cops gets together with a woman, he's happy to be with her, and then the other cops start giving him hell for it because she used to be a man. He gets disgusted and angry, goes over to her place, and she lectures him about it and sets him straight, tells him to figure out if he wants to be with her, but don't try to turn who I am into some kind of thing I did to you, or make me feel bad about it. He sort of accepts it, because she clearly has a point, and that's the end of the episode.
Hill Street Blues, man.
