What's interesting to me is that if we're able to accept the idea that mass social media-induced illness can be developed just by virtue of video watching TikTok or YouTube, then this opens new doors to examining the behaviour of other illnesses such as gender dysphoria that are statistically over represented. This is probably going to get downvoted to oblivion, because nobody wants to confront the idea that we can _…
I understand gender dysphoria (as opposed to body dysphoria/dysmorphia in a stricter sense) to be a mismatch between someone's own preferences, interests etc. inasfar as they touch on categories that society has declared to be gendered, and society's expectations of the same - at least those of your local bubble of society.
This means there are two non-mutually-exclusive ways to make the lives of gender dysphoric people better: (1) let them change themselves (many options from pronouns to hormones and surgery), or (2) change society's expectations. Out of sympathy for people suffering from gender dysphoria, I wish for a bit more of (2) in the world.
Even in a vastly improved society, there will be people who decide that medical changes such as hormones/surgery are right for them, and as far as possible we should support them. These people existed, in small numbers, before "trans" was cool, and they will still exist when the media interest has picked up some new favourite category. (By analogy, Tourette's syndrome is also a real thing that existed before the internet, and will still exist when this particular media spike has died down.)
