The main difference between the original sub cultures and the new ones is the Internet. Punks, Goths and New Romantics had to work hard to feed their interest in the real world, meeting up, DIY costumes, saving up for gig tickets etc. And it was a subversive rebellion thing - the shock element had a political thrust as well.
These days (Christ, I'm turning into my grandmothers - but perhaps that's not an entirely bad thing as thrmey were pretty wise crones) every whim can be satisfied at the click of a button. There weren't any Therians because who the feck knew what a Therian was?
Obviously it's nice for people to find "their people" and social isolation is an unhealthy thing but these days how do you know who you're connecting with on the Web? If they're even real - or a bot generated to steer one towards the current zeitgeist and whatever colour of pound generation is this week's trend?
A good proportion of Goths / punks hung up their studs and PVC and look fondly back on their wild youth. Some of us didn't but hey, we're at best the entertainment and at worst a terrible warning.
And that is where much of the subject of this thread will likely go too. But children need proper guidance when it goes a step further from imaginative "play" and starts potentially fucking with their perception of reality.
Litter trays may be a myth, and the odd set of ears and tail blown out of proportion, but as the whole trans debate has shown, the way to hell can very much be paved with good intentions (and capitalism without thought or compassion).
I feel for parents these days, I really do, and also for the children struggling with the world we live in. I can choose to opt out and do for the most part because I'm too old for this shit. But I remember peer pressure and loneliness and still occasionally have existential crises because I struggle to "get with the programne" because it changes every five minutes.
So hats off to those navigating the stormy seas of adolescence in this crazy world, both parents and tweens / teens. It's certainly above my paygrade these days.
