Nah that’s in-group jargon. In social justice circles “performative” implies superficial behavior without proper motives. For example, Nike changing their logo to a rainbow variant during pride month to sell more shoes would be “performative support” of queer culture.
In this context, I would guess it’s tongue-in-cheek, self-aware humor, since such a broad stroke would be pretty obviously unfair to many gender-nonconformist folks (as if their preferred aesthetic is all just a ruse to get laid). It’s more likely they’re celebrating the trend of non-binary aesthetics, just doing it in a humorous way.



Lol same vibe. Like wiggling eyebrows everywhere. “…is this… problematic…??”
