The sheer existence of established and (partially) self-reinforcing sets of cultural standards doesn't strike me as a good basis to explore the fundamental complement of it all, or to describe it altogether as something assuredly misleading and "bad". This should be especially apparent if you've ever tried creating something that is self-justifying (it's usually a hard, valuable, and sought after effort).
Put differently, while an idea being established and self-justifying doesn't necessarily mean it's exclusive in these traits and should be bolted in, sure, an idea being fringe also doesn't necessarily mean it's unjustly fringe at all, or that it's being unfairly discriminated against. To claim so without evidence is little more than conspiratorial thinking and self-victimization.
It further sounds really quite self-serving to paint e.g. me as some misguided sheep part of some malicious cabal for this. It's a little more than just a variation on the all too common ill faith ways of argumentation; mixing in the semantic specifics of psychedelic experiences, name dropping people, movements, and quotes, and deferring to a "specific" culture's particularities serves at most as a distraction from this.
