This resonated with me:
When my mom came down with paranoid schizophrenia and got obsessed with conspiracies, we used to say of people like her "they have mental health conditions and need help." But the conspiracy theories that wrecked her life and took her from her career as a Cornell-educated cancer researcher, were actually somewhat plausible: she believed the Russians may be bugging our telephone lines.
Now when people promote insane conspiracy theories about alien sex or whatever, we shrug and say "oh, someone's been in Facebook Groups or watching Fox News." And yet those conspiracy theories are less plausible than my mom believing in Russian spying.
Or, we say, freedom of the press, let the reader beware. The problem with that, as every doctor can attest, is the death and despair that follow. Even Twitter, which was founded on the idea of freedom of expression, has to put warnings on some conspiracies — like Covid is a democratic hoax and will disappear — or block the accounts of people who post that stuff to keep too many people from dying.
