What's different here is that it's bottom up as well as top down.
Top down scandals have always been with us...I don't recall anyone back in the day demanding to have their brains selectively sliced or shocked. These medical "solutions" were one way, imposed top down by doctors.
Ok, maybe people did demand sleeping tabs and tranqs etc in industrial quantities, but it was still the medical industry that promulgated the trade.
However trans looks like the first phenomenon where patient and doctor are in "perfect harmony". As much top down (diagnosis plus affirmation therapy, puberty blockers, cross sex hormones, surgery etc recommended) as much as bottom up (kids demanding, parents and medics acquiescing)
The patient comes in with a self diagnosis, made online, via teen peer group, with the help of bad actors (Jeffrey Marsh, we see you), and full acquiescence/red carpet rolled out by GIDS, Mermaids, Gender GP etc.
And a whole societal structure mediated to mop your brow, tell you you're special, and that you'll be the first generation not to be let down by heartless adults.
Never discount how many Gen X and Millennial parents were ignored and belittled by their Boomer and Greatest Generation parents, they were never ever gonna let their kids down, even it meant instant affirmation of the new trans ID thing.
Social media just adds to the wildfire nature of the phenomenon, maybe ramped up the ROGD side of things.
How prevalent was anorexia, bulimia, cutting, self harm, glue sniffing, Es, back in the day when the internet didn't exist?
