1. You can't just criminalize the spreading of one kind of mis/disinformation. Any move to criminalize anti-vaccine information will thus have huge social and humnan rights consequences
2. Even if you did criminalize only anti-vaccine sentiment, who would take the time and trouble to chase the thousands of miscreants?
3. "anti-vaccine" is subject to degrees: from the really huge whoppers to the slight slurs. Impossible to draw the criminalization line.
4. I watched Kazuo Ishiguro's launch of his new novel Klara and the Sun last night, and he noted that all writers of fiction were engaged in what he called "emotional truth" - dedicated to getting people to believe in fictions and fictional characters. He wondered about the role of novellists like himself in creating what we could call the "fake newsiverse": in which anti-vaxxers flourish.
Beware you don't kill all fictions while trying to exterminate some!
