The American right, including Jay Bhattacharya, is trying to weaponize free speech by crying censorship.
But freedom of speech isn't freedom of reach.
To fight back, scientific institutions should say that junk science is junk.

Saying bad ideas are bad isn't censorship
The core goal is a free and fair public debate, and billionaires promoting their favored speech tilts the free marketplace of ideas.

Bhattacharya hedging on vaccines? If only there were some way to know this would happen before he was appointed NIH Director...
Trump's pick for NIH director, Jay Bhattacharya, sometimes says positive things about certain childhood vaccines. Can we count on him as a counterweight to RFK Jr's anti-vaccine agenda?
He campaigned for RFK and has a tendency to get really quiet/confused when faced with vaccine lies directly. 🧵

Implicit in this assumption is the idea that every individual's physiology is so unique that it demands unique care.
