none of this would have been considered mentally sane, even a few decades back

Try years. You don't even need to go back decades, a few years does it.

Just look at stuff like hormones and surgeries for "trans kids," or schools and doctors operating without parental consent, or "biological sex isn't real" arguments. All the stuff they claimed wasn't happening, would never happen, which was abhorrent and they didn't want...is now happening, is a good thing, and is necessary and lifesaving. And safe and effective, of course.
