Don't give it too much relevance. Tiktok and social media can amplify unusual beliefs or attitudes in ways that aren't helpful, or actually reflective of the real world. Furthermore, some people subconsciously or conscious are using Tiktok to get attention. Attention, positive or negative, gets monetized on these platforms.
I've seen alot of purple haired types at my local coffee shop, with more nose rings than my shower curtain, but, I've never met one of these "therians".
This. I'm friends with plenty of people with dyed hair and piercings--while I've never really dyed my hair other than dying it black a couple times when I was younger (in HS I tried to bleach my hair, which in the late 90s was super in fashion, the result was bright orange deep fried hair, so I haven't tried anything too crazy since); and until just a couple years ago I had several piercings--ears and eyebrow, I removed them when I was hired onto my current occupation. I don't know if this comes to a surprise to those familiar with me on this website, but I've tended toward a more "alternative" aesthetic, and a part of me is still that punk rock and ska loving kid listening to Five Iron Frenzy and NOFX in the late 90s and early 2000s. So dyed hair, piercings, tattoos--that describes most of the people in my life for the last two+ decades.
But just to contribute: Never met anyone that thinks they're an animal. I know that "furries" exist, but it is an incredibly small subculture. Over a decade ago people who supposedly identified as animals or fantasy creatures calling themselves "otherkin" was a thing in some niche online spaces--but it was never a
thing. If "therian" is the term used for something similar these days, then it's definitely in the same vein: niche online subculture with a handful of online spaces.
What there definitely isn't: Hordes of teenagers galloping around at all hours of the night and this being some great worry that parents, civic leaders, or society in general should be concerned about.
It's kids being weird, and of the tiny, tiny, tiny number who are currently part of this subculture, we can all sleep comfortably at night knowing that 99% of them will grow out of it by the time they either graduate high school, or somewhere along the way in college.
Now, if your 40 year old child still living in the basement (who doesn't have any debilitating mental trauma or illness) who refuses to get a job, and insists they are StarPuppy3000 or something, well ok, probably time to nudge them toward therapy. But kids? Kids are kids.
