To be clear, they will 'make the proof' that Tylenol causes autism by controlling who does the studies and who reports the results.

They have built a mechanism to 'make the proof' for whatever they want so say. About protestors, about elections, about immigrants.

We have to keep speaking truth.

None of us should feel exempt or invulnerable, because if they can do this to our neighbors, they can come for us, too. That said, those of us who are not presently among those being targeted should not focus on our own fear and vulnerability. We should support those in the immediate path of harm.
