While what you're saying sounds like a reasonable enough stance on the face of it, keep in mind that this would deeply fuck over closeted queer folks among other marginalized groups.
It would. Currently they and everyone else are getting deeply fucked because the signal to noise ratio on the internet has been obliterated and everyone is being manipulated all the time by misinformation from humans lying to bots.
I think the trade off for a lack of anonymity is worth it. This is crass and old but the penny arcade guys identified this decades ago
I agree misinformation is a big problem. Possibly the biggest problem of our time, right next to global warming. But as it stands now, as a queer person, you can find a spot on the internet with like-minded people. Even when closeted. Hell when closeted it's the only place you can find like-minded people.
If we require people identify themselves online you drive all closeted queer people away, into solitude, into feeling no one will ever understand them. That's not worth the price of admission.
