i guess it must have also been sad when parents allowed kids to identify as sinister. meaning left-handed, of course. one moment, it was rightfully shunned, the next moment sinister people started getting everywhere and it was growing at an alarming rate, threatening to take over society...
...until it hit 12.5%, where it flatlined and stayed ever since. turns out if you don't bully people into repressing a trait they're born with, you'll see a meteoric rise in the amount of people you now accept, when they stop (rightfully) fearing that you'll repress them. today, it's beyond trivial that if you think there ever has been a point in history where one eight of all people haven't been left-handed, you're just a moron, but your rhetoric would perfectly fit the era when that started to be accepted.
we don't know exactly how many people are trans, but the sharp rise you see and characterize as "currently relevant in social media" is simply due to society (mostly) letting people finally be who they always have been. realistically, trans people are a minority, but that doesn't mean they don't have the same right to be themselves that you and i already enjoy simply for having been born into the majority.
