Kind of a tangent off your point but you’re referencing the "girls do not exist on the internet" phrase like it was used by people to say don’t bring your identity onto an anonymous forum.
Was that how it was used? Back in my forum and chan days when that phrase was common I only saw it used to explicitly try to force women off the internet. It was usually quickly followed up with “tits or gtfo” for instance and I never saw an equivalent push on anyone mentioning they were a man
I've always understood "tits or gtfo" to suggest that if you are mentioning you are a girl then do something related to it (show breasts) or else shut up about being a girl when its not relevant.
That's on the charitable side. It reads to me more like "a woman's acceptance in this community is predicated on her providing sexual favours". But your interpretation still reveals an issue: men are allowed to express themselves in small (and often large) ways that are "not relevant", so why this (pervasive) attitude when women do it?
I cant recall a single instance where the woman in question delivered and then wasn't met with immediate derision and misogny. It was a pretty explicit anti woman statement
