It is a mistake to think pushing everybody to talk only in private will increase the diversity and quality of discourse. It will NOT, it will collapse conversations into simpler more reductive narratives.

I feel like over the last two decades everyone on the internet was pushed to talk only in public, even more so, on the few biggest platforms only.
