That’s an interesting categorization of the sub-cultures/scenes you listed. Are there any sub-cultures you would classify as “other” (in the sense of being other than the status quo of its era) and having introspection and awareness?
Furries? I mean, their whole schtick is that they feel like a different animal trapped in a human body. That's pretty introspective and self-aware, I guess.
The funniest part is where it's asserted that these "fads" were "played out" by the time they gained any popularity. Which was only true of emos; they swept aside everything that made grunge and goth culture aesthetically interesting, and adopted normcore instead. Well, true of hipsters, too, but "before it was cool" was their whole thing; the played-out nature of the fad was effectively a joke on everybody who cared enough to be bothered by shat beer and silly facial hair.
But, no, I don't think you're right about furries. They aren't "animals trapped in a human's body," that's a mischaracterization used by edgelords who dunk on transgender people. Furries extremely diverse in their internal and external narratives, and I won't attempt to provide an alternative characterization.
