When I was young there was no trans, no autism, no lots of stuff, because they hadn't been identified and talked about. If you were a bit odd, you were a bit odd, and everyone put up with it. Those who were a bit odd might have felt fairly comfortable not having attention drawn to themselves, but I suspect many would have suffered and relied on religion or suicide to enable them to cope. Nowadays they realise that there are many people in the same boat and I imagine that can be a comfort to them.
It's sad that there are many 'normal' people who feel so uncomfortable about any kind of difference (gender, sexual preference, skin colour, funny foreign accent ....) that they actually condemn or insult people about this.
