Absolutely! A lot of this knowledge has become less common even among trans people as people who transitioned in that era are often still uncomfortable being open and self advocating because they’d been taught so strongly not to, meanwhile once it became easier and more acceptable they wound up vastly outnumbered. Also aids killed a lot of the open trans people.

And yeah I think it’s really easy for people, such as the one you were replying to, who don’t know much to just observe that there sure seem to be a lot more of us these days and make a guess as to why that fits within narratives that make sense to them. I can’t even be too mad, as that’s kinda just how people work. What irritates me is how often such narratives are prioritized to equal to or greater than informed and cohesive positions. And yeah there’s a reason we like to pull out the graph of rate of left handedness over time.

And I should note, I’m not even saying that hormone disrupters in the water aren’t increasing the rates of trans people, it’s a plausible hypothesis, it’s just that you’d need to control for a lot of social variables and that’s very difficult.
