A lot of peoples' complaints about ostensible public spaces on the internet aren't wrong about the malaise present in those spaces, but they do posit a clean and universal binary between social and every other kind of space, in which social spaces notionally consist of a totalised freedom to be both authentic and everything that you are, all identities and social roles expressed to the maximum simultaneously, and that's, sorry, that's never existed anywhere. Humans are complex social actors, with an array of overlapping (and non-overlapping!) valence shells of social identities held by each single person. We are different things to different people and that's not just okay, it's normal and it's healthy and genuinely fine. It's a fact, not a symptom of oppression — though oppression frequently involves eliminating spaces where specific valences can be expressed.
The thing you're looking for cannot be a single space where you are free to be maximally everything all at once; that's just not how anything works.
